**Contactors**
## **Data according to IEC 947-4-1, EN 60947-4-1, VDE 0660**
## **Contact Life**
For selection of the suitable contactor-type according to supply voltage, power rating and application (utilization category AC1, AC3 or AC4) use contact life characteristic diagram.
For the most common supply voltages four scales of power ratings Pn are provided for each utilization category.
Select contactor-type according to utilization category **AC3** (breaking current Ia = Ie) using the **motor rating** scales to the right, according to utilization category **AC4** (breaking current Ia= 6 x Ie) using the **motor rating** scales to the left.[*1]
Select contactor-type according to utilization category **AC1** (breaking current Ia = Ie/AC1) using the **breaking current** scale.[*1]
For contactors frequently used under AC3/AC4-mixed service conditions calculate contact life with the formula:
**==> picture [108 x 32] intentionally omitted <==**
M = Contact life (switching cycles) for AC3/AC4-mixed operations AC3 = Contact life (switching cycles) for AC3 operations (normal switching conditions). Breaking current Ia = rated motor current In.
AC4 = Contact life (switching cycles) for AC4 operations (inching).
Breaking current Ia= multiples of rated motor current In.
%AC4 = Percents of AC4-operations related to the total cycles.
1. Pay attention to the approved rated values of the selected contactor according to the national approvals

**Thermal Overload Relays** , tripping times for selection to motors of protection degree EEx e **Relays With Standard Tripping Characteristic**
All tripping times of overload relays J7TKN-A are shorter than the minimum values of the tE time for motors of protection degree EEx e acc. to EN 50019 and therefore are suitable for all motors of protection degree EEx e. For these overload relays the selection on basis of tripping curves is thereby not necessary.

Typical tripping curve for overload relay J7TKN-A Minimum values of tE time (motor) acc. to EN50019 ratio IA/IN
Labels of tripping curves for each setting range, sized 148x105mm (self-adhesive) are available on request.
When selecting a standard overload, refer to the tripping curve. Determine the values of the starting current ratio **IA/IN** and the time **tE** which is marked on the label of the motor. The overload must trip within the **tE** time, which means that the tripping curve from cold condition must be (20% due to tolerance) below the coordination point **IA/ IN** and the time **tE** . **IA** = Starting current of motor **IN** = Rated current of motor **tE** = tE-time of motor

## **Temperature Compensation**
In case of higher ambient temperature use the following formula: (Ambient temperature - 20) x 0.125 = correction factor in % of the
full load motor current
Example: Ambient temperature 70°C, full load motor current 7A (70 - 20) x 0.125 = 6.25% Setting value: 7A + 6,25% = 7.44A

## **Technical Data according to IEC/EN 60947-1, 60947-2, 60947-4-1 and VDE 0660**
This table shows the rated ultimate short-circuit breaking capacity Icu and the rated service short-circuit breaking capacity Ics of the J7MN circuit-breakers with different operational voltages as a function of the rated current In of the circuit-breakers.
The circuit-breakers can be fed at the top or bottom supply terminals without any reduction of the rated data.
If the short-circuit current exceeds the rated short-circuit breaking capacity of the circuit-breaker specified in the tables at the installation point, a back-up fuse is to be used.
The maximum rated current for the back-up fuse is specified in the tables. These fuses are only suitable for the short-circuit-currents as indicated on the fuses.

## **Description**
J7MN circuit-breakers are compact, current-limiting circuit-breakers which are optimised for load feeders. The circuit-breakers are used for switching and protecting three-phase induction motors of up to 18,5 kW at AC 400 V and for loads with rated currents of up to 40 A.
## **Construction**
The circuit-breakers are available in three sizes:
J7MN-12 overall width 45 mm. Max. rated current 12 A. Suitable for 3-phase induction motors of up to 5.5 kW at voltages of 400 V AC. J7MN-25 overall width 45 mm. Max. rated current 25 A. Suitable for 3-phase induction motors of up to 11 kW at voltages of 400 V AC. J7MN-50 overall width 55 mm. Max. rated current 40 A. Suitable for 3-phase induction motors of up to 18,5 kW at voltages of 400 V AC.
## **Releases**
Circuit-breakers J7MN are equipped with bimetallic-based, inversetime delayed overload releases and with instantaneous overcurrent releases (electromagnetic short-circuit releases).
The overload releases can be set in accordance with the load current. The overcurrent releases are permanently set to a value 13 times the rated current and thus enable trouble-free start-up of motors.
The scale cover can be sealed to prevent unauthorized adjustments to the set current.
## **Operating mechanisms**
circuit-breakers J7MN-12 are actuated via a switch operating mechanism and circuit-breakers J7MN-25 and J7MN-50 via a rotary operating mechanism. If the circuit-breaker trips, the rotary operating mechanism switches to the tripped position to indicate this. Before the circuit-breaker is reclosed, the rotary operating mechanism must be reset to the 0 position by hand, in order to prevent the former from closing by mistake before the fault has been cleared.
In the case of circuit-breakers with rotary operating mechanisms, there is an electrical signal via a signalling switch to indicate that the circuit-breaker has tripped.
## **Short-circuit protection**
The short-circuit releases of J7MN circuit-breakers disconnect the faulty load feeder from the system in the event of a short circuit and thus prevent any further damage.
Circuit-breakers with a short-circuit breaking capacity of 50 kA or 100 kA at a voltage of 400 V AC are practically short-circuit-proof at this voltage, as higher short-circuit currents are not usually encountered at the installation point.
Back-up fuses are only necessary if the short-circuit current at the installation point exceeds the rated ultimate short-circuit breaking capacity of the circuit-breakers.
## **Motor protection**
The tripping characteristics of J7MN circuit-breakers are designed mainly to protect three-phase induction motors. The circuit-breakers are therefore also referred to as motor circuit-breakers. The current of the motor to be protected is set with the aid of the scale.
Circuit-breakers with thermal overload releases are normally designed in accordance with release Class 10.
## **Line protection**
J7MN circuit-breakers for motor protection are also suitable for line protection. In order to prevent premature tripping due to phase failure sensitivity, the three conducting paths must always be uniformly loaded. The conducting paths must be connected in series in the case of single-phase loads.
The J7MN circuit-breakers meet the isolation conditions of IEC 60 947-3 as well as the additional test conditions for circuitbreakers with isolation characteristics specified in IEC 60 947-2. Taking IEC 60 204-1 into consideration, they can thus be implemented as main and EMERGENCY STOP switches.
Door-coupling rotary operating mechanism do not fulfil the isolation characteristics specified in IEC 60 947-2. Door-coupling rotary operating mechanism according isolation characteristics specified in IEC 60 947-2 on request.
All operating mechanisms can be locked in the 0 position with a padlock (shackle diameter 3.5 to 4.5 mm).
The J7MN circuit-breakers fulfil the isolation characteristics specified in IEC 60 947-2.
## **Operating conditions**
Circuit-breakers J7MN are suitable for use in any climate. They are designed for operation in enclosed rooms under normal conditions (e. g. no dust, corrosive vapours or harmful gases). Suitable enclosures must be provided for installation in dusty or damp rooms.
Circuit-breakers J7MN can also be fed from below. The standards in accordance with which the circuit-breakers are constructed, the permissible ambient temperatures, the maximum making and breaking capacities, the tripping currents and other boundary conditions can be found in the technical data and tripping characteristics.
Since the operational currents, starting currents and current peaks vary as a result of the inrush current, even in the case of motors with identical output ratings, the values specified for these output ratings in the selection tables are intended as a guide only. The specific rated and start-up data of the motor to be protected is always paramount to the choice of the most suitable circuit-breaker.
In order to prevent premature tripping due to phase failure sensitivity, the circuit-breakers should always be connected in such a way that current flows through all three main conducting paths.
> Motor Protection Circuit Breaker (MPCB) **J7MN** H-79
## **Characteristics**
The time/current characteristic, the current limiting characteristics and the I²t characteristics were determined in accordance with DIN VDE 0660 and IEC 60 947.
The tripping characteristic of the inverse-time delayed overload releases (thermal overload releases or ’a’ releases) for DC and AC with a frequency of 0 to 400 Hz also apply to the time/current characteristic.
The characteristics apply to the cold state. At operating temperature, the tripping times of the thermal releases are reduced to approximately 25 %.
Under normal operating conditions, all three poles of the device must be loaded. The three main conducting paths must be connected in series in order to protect single-phase or DC loads.
With 3-pole loading, the maximum deviation in the tripping time for 3 times the setting current and upwards is ± 20 % and thus in accordance with DIN VDE 0165.
The tripping characteristics for the instantaneous, electromagnetic overcurrent releases (short-circuit releases or ’n’ releases) are based on the rated current In, which is also the maximum value of the setting range for circuit-breakers with adjustable overload releases. If the current is set to a lower value, the tripping current of the ’n’ release is increased by a corresponding factor.
The characteristics of the electromagnetic overcurrent releases apply to frequencies of 50/60 Hz. Appropriate correction factors must be used for lower frequencies up to 16 2/3 Hz, for higher frequencies up to 400 Hz and for DC.
The characteristic shown here is a schematic representation of circuit-breakers for all ranges.
Time/current characteristics, current limiting characteristics and I²t characteristics are available on request.

## ● **Precautions**
## ■ **Notice**
Use under rated condition, otherwise contactors will not only cause malfunction, but also cause a fire or damage the contactor.
Life period of contactor depends on the operating application. Please check the electrical life under real application in advance. If you continue to use malfunctioning contactor, a fire or breakdown may occur.
Do not use a contactor or thermal relay which has been dropped or dismantled. Doing so may cause malfunction or a fire.
Make sure to shut off power supply to contactors before wiring or replacing.
Do not operate the actuator of a contactor manually. Doing so may cause contact welding by chattering or burn out by arc.
Do not miss-wire or miss-charge the power supply, otherwise the contactor does not work correctly.
Do not operate in places with explosive or flammable gas, otherwise a fire or explosion may occur by arc or heating from contactor.
Make sure to use the circuit well considered about safety, in case there is any possibility to cause secondary disaster by contact trouble (welding, faulty contact).
Do not supply short-circuit current to electromagnetic switch (contactor with thermal relay). Doing so may result failure in heater of thermal relay. Please use short-circuit protection like fuse or protective circuit breaker.
**Unless otherwise stated in the catalogue, modifications, especially those of stated values, sizes and weights are subject to alternation.**
**Diagrams and tables are subject to alternation and not to be regarded as binding drawings.**
## ■ **Correct use**
## **General use**
Unexpected malfunction may occur in real application. Please carry out as many tests as possible.
Ratings in this catalogue measured under the condition according to IEC unless otherwise specified. In cases of check by real application, please carry out the test under the same condition as expected in the actual application.
## **Selection**
## **Coil specification**
Please select suitable coil to circuit design, otherwise malfunction may occur or coil may have a burn out by overvoltage etc.
## **Type**
Please check contact ratings, switching capacity, thermal characteristics etc. when selecting product type.
## **Thermal relay**
Motor current differs by supplier, type, number of poles, frequency. Please confirm operational current level.
## **Coil surge suppressor**
Coil surge suppressor type should be selected by contactor type, auxiliary relay type and applied voltage. Make sure to use defined each contactor.
In case of installing coil surge suppressor, please check the actual circuit because the release time will be delayed.
## **Electrical life expectancy**
Electrical life expectancy tests in this catalogue are based on IEC.
## **Circuit design**
## **Supplied voltage waveform for input**
Make sure to apply and remove the voltage instantly. Do not use under the condition that the coil voltage waveform increases or decreases gradually.
## **In case of DC contactor use (input voltage ripple)**
Please use DC contactor input voltage with a ripple ratio less than 5%. Excessive ripple (pulsating current) may cause contact welding.
## **Fluctuation of input voltage**
Make sure to supply sufficient voltage to actuate contactors properly. Continuous supply of insufficient voltage results in excessive heating and may cause burn out of coil.
## **Maximum applied voltage**
Do not supply the voltage over the maximum rated voltage, otherwise burn out or insulation failure may occur.
The temperature inside control panel has much influence to the coil temperature, so make sure not to exceed the specified value in the catalogue.
Basically rated voltage should be supplied to coil. To supply higher voltage than rated would result in shorter electrical life, even if it is lower than the maximum rated voltage.
## **Reverse**
Make sure to use reversible contactors for reverse operation.
Make sure to use interlock device in reverse operation by two contactors, otherwise short circuit current may burn out or give damage to contactors and motors.
**Appendix**
H-83
## **Installation**
## **Mounting**
Make sure to use specified wire size, mounting screw size, mounting screw number, and DIN rail size.
## **Tightening Screw**
Tighten each screw securely by specified tightening torque. Loose tightening may cause a fire by excessive heating.
## **Combination**
Please use only OMRON product combinations in case of thermal relay, timer block and auxiliary contact block etc. Wrong-combinations may result in damage to contactors.
## **Mounting direction**
Some products have a defined specific mounting direction. Please refer to datasheet before use.
## **Operation ambience**
## **Dust**
Dust on the surface of the contacts could result in contact malfunctioning. Take countermeasure in excessive dusty surrounding.
## **Temperature, humidity**
Use contactors within the temperature and humidity conditions specified in datasheet. To use or store contactor in excessive temperature or humidity may result in malfunction of contact by organic film composed by sulfication and oxidation on the surface of the contacts.
Use contactors within the temperature and humidity conditions specified in the datasheet, to prevent contactors from insulation resistance failure by condensation or insulation resistance deterioration by tracking.
## **Gas**
NH3, H2S, SO2, CI2, Si and NO2 have bad effects on a contactor. With these gases, a corrosive metal film ist generated on the surface of the contacts and could result in contact malfunctioning. Use a contactor in low humidity and no corrosive gas surroundings.
## **Oil**
Do not use a contactor in places where oil is sprayed onto the contactor. It will cause cracks on polymer parts.
## **Shock and vibration**
Do not use a contactor in places where there is excessive shock or vibration. It may cause malfunctioning.
## **Storage**
Store contactors in a place with no direct sunshine or ultraviolet rays. It will cause crack on polymer parts.
When contactors are to be stored for a long time, they must be stored with care. Though it generally depends where contactors are stored, deterioration of contacts may occur after long storage. Please check the characteristics before use after long time storage.

## ● **European Standards**
## ■ **IEC 947, EN 60947**
## **European Standards for Low-Voltage Switchgear**
For Europe and most other industrial countries of the world, the new IEC 947 and EN 60 947 specifications for low-voltage switchgear have unified the regulations which previously varied from nation to nation.
This required the introduction of new terms, and new test methods and utilization categories. The new specifications are aimed primarily at manufacturers. However, the user also will come across new technical terms and data in the manufacturers’ catalogues and on the devices themselves which are important for the selection and application of the devices. The present paper deals with the currently published specifications. Further specifications and supplements are in preparation.
Since 1993, all low-voltage switchgear purchased in Europe had to satisfy the EN 60 947 European Standard. Installations in existence prior to 1993 are not affected by the standard and need not to be refitted with new devices. Devices constructed and tested to the IEC standards and EN standards can be used worldwide, with the exception of the USA and Canada. In these countries UL and CSA specifications continue to apply. Switchgear which conforms to IEC 947 and EN 60 947 and which has, in addition, UL- and CSA approvals, in the meantime has entered the market.

**Note1:** If the switching device has a making and/or breaking capacity, the figures for the current and the power factor (time constants) must be stated by the manufacturer. **2:** A: frequent operation, B: infrequent operation.
## **Protection against electrical shock, to IEC 536**
IEC 536 covers the setting up of electrical apparatus, and its arrangement in electrical installations with rated voltages up to 1000 VAC and 1500 VDC, with regard to protection against direct contact where operating elements such as push-buttons and switches are located in the vicinity of live parts.
“Finger-proofing” relates only to the operating device, and only in the normal direction of operation. A clearance of at least 30 mm radius from the centre point of the device to any live parts, must be ensured.
The IP 20 degree of protection is superior to “finger-proofing” in that it embodies protection against contact with electrical apparatus in any direction. Devices which are “finger-proof” and of IP 00 degree of protection can be provided with further protection against contact in the form of shrouding, if so desired.
## **Damp heat, constant, to IEC 68 Part 2-3**
In this test, the effects of a constant high level of humidity (93 +2/-3%) and a constant temperature (40 ±2)°C over a prescribed duration, are observed.
## **Damp heat, cyclic, to IEC 68 Part 2 - 30, Test Db**
This test is used to assess the suitability of electrical products for operation and storage at high relative humidity levels, in conjunction with cyclic temperature fluctuation. A test cycle consists of 12 hours at 40 ±2°C, with relative humidity of 93 ±3%, and 12 hours at 25 ±3°C, with the relative humidity of at least 95%.
## **Ambient temperature**
Ambient temperature is the temperature of the room (e.g. factory bay or switchgear room), in which the open or enclosed device is installed, a prerequisite being that this temperature is not significantly influenced by the heat losses from the device.

The prospective short-circuit current which, depending on the rated operationaI voltage, a circuit-breaker is capable of breaking repeatedly (test cycle: O - CO - CO; previousIy P-2). After interrupting this current vaIue, the circuit-breaker must be capable, despite its own thermal level having increased, of continuing to carry and disconnect in the event of overIoading, the rated uninterrupted current.
## **Rating or rated power**
## **(IEC 947-1; 4.3.2.3)**
The rated operational power which an equipment is capable of switching at the associated rated operational voItage in accordance with the utilization category.
For example: motor contactor utilization category AC-3: 37 kW at 400 V.
## **Rated operational voltage Ue**
## **(IEC 947-1; 4.3.1.1)**
The voItage to which the characteristics of an equipment are referred. The rated operational current must not in any case exceed the rated insulation voltage.
Reference is therefore made aIongside each such term to the reIevant section of the standard, e.g. IEC 947-1 in addition, IEV numbers are given to enable you to find foreign language equivalents in the International EIectrotechnicaI Vocabulary (IEG 50), if required.
## **Rated operational current Ie**
## **(IEC 947-1; 4.3.2.3)**
The current which an equipment is capabIe of carrying taking into account the rated operational current, duration of operation, utilization category and ambient temperature.
## **Rated uninterrupted current Iu**
## **(IEC 947-1; 4.3.2.4)**
The vaIue of current which an equipment can carry in uninterrupted duty (i.e. for weeks, months or years).
## **Rated making capacity**
## **(IEC 947-1; 4.3.5.2)**
The vaIue of current which an equipment is capabIe of switching On in accordance with the utilization category and at the rated operational voltage.
## **Rated frequency**
## **(IEC 847-1; 4,3.3)**
The frequency for which an equipment is designed and to which the other characteristic vaIues are referred.

The maximum prospective fault current which a circuit-breaker is capable of interrupting (test cycIe: O - CO; previously P-1)
## **Rated insulation voltage Ui**
## **(IEG 947-1; 4.3.1 .2)**
The voltage to which insulation tests and creepage distances of an equipment are referred. The maximum operationaI voltage must not in any case exceed the rated insulation voltage.
## **Rated short-circuit breaking capacity Icn (IEC 947-1; 4.3.6.3)**
The maximum value of current which an equipment is capable of switching Off at rated operational voItage and rated frequency, and without sustaining damage. It is expressed as r.m.s. value.
## **Motor rating**
## **(IEC 947-1; 4.3.2.3)**
Power output of a motor at the associated operational voltage.
## **Rated control supply voltage Us**
## **(IEC 947-1; 4.5.1)**
The voltage applied to the input terminals of the control circuit of an equipment. Due to the presence of transformers or resistors in the control circuit, this may differ from the rated actuating (control circuit) voltage.
**Appendix**
H-89
## **Rated impulse withstand voltage Uimp (IEC 947-1; 4.3.1 .3)**
Measures the stability of the internal clearances of an equipment against overvoltage peaks. The utilization of suitable switchgear can ensure that overvoltages are prevented from transferring from the mains to deenergized system sections within it.
## **Rated current In**
## **(of a circuit-breaker) (IEC 947-2; 4.3.2.3)**
For circuit-breakers, this current value is equal to the uninterrupted current and the conventional free air thermaI current.
## **Protection against direct contact**
Design measures incorporated into equipment in order to prevent direct contact, i.e. without tools, with live parts of a system (finger proof, back-of-hand proof).
## **Control circuit reliability**
Measures the probability of switching states arising during the lifespan of a contact, which would be interpreted as faults by downstream electronic controllers (PLCs). Control circuit reliability is expressed in values based on tests using standard limit values for signal inputs.
## **Damp heat, constant**
This test subjects the equipment to an ambient temperature of 40°C at a constant humidity of 93%. At set intervals during the test, the electrical and mechanical function of the equipment are examined.
## **Damp heat, cyclic**
This test subjects the equipment to cyclically changing climatic conditions: a cycle applies 40°C ambient temperature at 93% relative humidity for 12 hours, followed by 12 hours of 25°C at 95% relative humidity. At set intervals during the test, the electrical and mechanical function of the equipment are examined.
## **Finger proof**
An equipment whose live parts cannot be touched by the operator during actuation is termed finger proof. This also affects operator activity on neighbouring switching devices. The finger proof area of a push-actuated operating medium is a circular area of at least 30 mm radius around the actuating element, and vertical to the direction of actuation.
Within this circular area, touch-critical parts must be located at not less than 80 mm depth under the actuating level.
## **Utilization category**
## **(IEC 947-1; 2.1 .18/IEV 441-17-19)**
A combination of specified requirements relating to the condition in which the switching device or the fuse fulfills its purpose, selected to represent a characteristic group of practical applications. The specified requirements may concern, e.g. the values of making capacities, breaking capacities and other characteristic values, data concerning associated circuits, and the relevant conditions of use and behaviour.
## **(IEC 947-2; 4.4)**
For circuit-breakers, the utilization category denotes whether the equipment is designed for selectivity using time delay (category B) or not (category A).
## **Back-of-hand proof**
An equipment whose live parts cannot be touched by a sphere of 50 mm diameter, is regarded as back-of-hand proof.
## **Altitude**
The density of air decreases with increasing altitude, and this reduces its insulating capacity as well as its heat transfer capability. The rated operational voltage and current of switching devices, conductors and motors as well as the tripping behaviour of thermal overload relays are affected by this.
Upon request, OMRON ELECTRONICS will supply information as to the suitability or otherwise of switchgear for operation at altitudes above the 2000 m limit specified by the standard.
## **Conventional free air thermal current**
## **(IEC 947-1; 4.3.2.1)**
The maximum value of current which an equipment is capable of carrying for a minimum of eight hours without thermal overloading. As a rule, it corresponds to the maximum operational current.
## **Creepage path**
## **(IEC 947-1; 2.5.51/IEV 151-03-37)**
The shortest distance along the surface of the insulating material between two conductive parts. The creepage distance is determined by the rated insulation voltage, the pollution degree and the creepage current resistance of the material used.
## **Clearance**
## **(IEC 947-1; 2.5.46/IEV 441-17-31)**
The distance between two conductive parts along a string stretched the shortest way between these conductive parts. The clearance in air is determined by the rated impulse withstand voltage, overvoltage category and pollution degree.

H-90
## **Emergency-stop switching device**
Switching device within an emergency-stop circuit which is intended to prevent danger to persons, damage to machinery or working materials.
## **Opening delay**
## **(IEV 441-17-36)**
The interval of time between the specified instant of initiation of the opening operation and the instant when the arcing contacts have separated in all poles. The opening time is the sum of the tripping time and the inherent delay of the contacts.
## **Closing delay**
The interval of time between the instant of command and the first make operation of the contacts of the first pole to close. The closing delay is made up of the response delay and the closing time.
## **Shock resistance**
The capacity of an equipment to withstand pulse-like motions without changing its operating status or sustaining damage. No contact lifting must take place on devices in the On position, the main contacts must not knock against each other in the Off position. A safety switch must not trip, and control circuit switches must not change their switching status.
## **Safe isolation**
## **(IEC 536, DIN VDE 0106 Part 101)**
Isolation of circuits not carrying dangerous voltages (e.g. protective extra-low voltage) from circuits in which dangerous voltages flow. Such isolation is achieved by means of reinforced or double insulation which reliably prevents voltage transfer from one circuit to another. This might otherwise take place between main circuits and control circuits in switching devices or between transformer primary and secondary. ”Safe isolation” is a priority requirement for safety circuits and functional low-voltage circuits.
## **Isolating function**
## **(IEC 947-1; 2.1.19)**
Equipments are deemed to possess this isolating function provided their switching contacts when in the open position, achieve the separation distance prescribed for the isolation of electrical circuits, and their creepage paths and clearance distances are of the required size. The power supply to the entire installation or a section of the installation can thus be cut off for safety reasons, e.g. during maintenance.
## **Tamper proof**
An emergency-stop switching device is regarded as tamper proof provided it cannot be reset without tools or via a prescribed procedure, after tripping has taken place. The device latches in the tripped position. Accidental or deliberate manipulation (inching) is thus ruled out.
## **Overvoltage category**
## **(IEC 947-1; 2.5.60)**
Conventional number for prospective overvoltages at the point of installation, as might be caused for example by the effect of lightning or switching processes. The overvoltage category applicable to industrial switchgear is III. The applicability of switchgear according to the overvoltage categories is defined as follows:
## **Overvoltage category IV:**
Use allowed directly at the termination point of the installation (directly affected by any lightning), e.g. at an overhead line connection point.
## **Overvoltage category III:**
Operating media with special requirements as to the serviceability for connection in fixed installations, which are protected by overvoltage diversion measures, e.g. circuit-breakers in low-voltage distribution systems or in control systems for industrial use.
## **Overvoltage category II:**
Power consumers for connection to fixed installations, e. g. household appliances, electrical tools.
## **Overvoltage category I:**
Operating media for connection to circuits containing overvoltage protection schemes, e.g. electronic devices.
## **Ambient temperature, open**
## **(IEV 441-11-13)**
Room temperature for example of the workshop or switch room in which the switching device is located.
## **Ambient temperature, enclosed**
## **(IEV 441-11-13)**
Temperature at which the switching device is capable of being operated within a closed housing. For this purpose, it must be taken into account that the heat losses of the device will add to the internal temperature rise within the enclosure.
## **Losses**
## **(IEV 151-03-18)**
The difference between the input power and the output power of a device. The main type of loss in electrical power distribution switchgear and operating media is current heat loss.
## **Pollution degree**
## **(IEC 947-1; 6./1.3.2)**
Conventional number for the prospective quantities of conductive dust and humidity which can lead to a reduction in the control circuit reliability of a device. The pollution degree is described by the following influencing factors:
## **Pollution degree 1:**
No pollution or only dry, non-conductive pollution occurs. The pollution does not affect the control circuit reliability.
## **Pollution degree 2:**
Usually, only non-conductive pollution. However, transient conductivity through condensation is to be expected.
## **Pollution degree 3:** (switchgear for industrial use)
Conductive pollution or dry, non-conductive pollution which is rendered conductive through condensation.
## **Pollution degree 4:**
The pollution leads to long-term conductivity, e.g. pollution by conductive dust, rain or snow.
**Appendix**
H-91
## **Coordination type**
Status of a switchgear combination (motor starter) during and after testing at **rated conditional current** :
## **Coordination Type “1“:**
- No risk to persons or installations
- No requirement for immediate readiness for renewed operation
- Damage to the starter is permissible
## **Coordination type “2“:**
- No risk to persons or installations
- Starter is capable of renewed operation
- No damage to the starter with the exception of a slight welding of the contacts, provided they can be separated without significant deformation.
## **Positive opening operation (IEC 947-1; 2.4.11/IEV 441-16-12)**
This opening operation is designed to ensure that auxiliary contacts of a switching device are always in the respective positions corresponding to the open or closed position of the main contacts. The contacts of a contactor are **interlocked opposing contacts** , pro-
vided they are mechanically linked in such a way as to ensure that normally open and normally closed contacts can never be closed simultaneously.
This arrangement must also ensure that minimum contact separation of 0.5 mm is maintained over the entire lifespan of the device, even during a fault, e.g. the welding of one contact.
The relevant German Trade Association requires the use of contactors with interlocked opposing contacts for control systems on power presses in the metal processing industry.
## **Positive/enforced**
## **operation/actuation**
This describes an arrangement where a link between the actuator and the switching element ensures that the force exerted on the actuator is transferred directly, i.e. without the intervention of sprung parts, onto the switching element.
## **Positive opening**
## **(IEC 947-1; 2.4.10/IEV 441-16-11)**
An opening operation which ensures that the main contacts of a mechanical switching device have attained the open position when the actuator is in the Off-position.

## Marking of auxiliary contacts
At several devices in UL-data are two voltages for auxiliary contacts mentioned (e. g.: 600 volts at same potential, 150 volts at different potentials). That means, if the voltage is higher than 150 volts, the control voltage applied to input terminals must be at the same potential

|6|Dust tight|Prevents ingress of dust.|
## **Terminal markings acc. to EN50011**
Auxiliary contacts of AC contactors and contacts of contactor relays and thermal overload relays are particularly marked. The terminal markings of normally-open contacts are printed as positive figures, they of normally-closed contacts as negative figures.
This gives a clear indication of the function of the contacts.
The figure below illustrates the determination of terminal markings for contactors with auxiliary contact blocks.
Sequence number Function number
The complete terminal marking according to EN 50011 and EN 50012 results from the sequence numbers on the contactor relay or ac contactor (2., 3.) and the function numbers on the auxiliary contact blocks (e. g. .1, .2, or .3, .4).

|6|Protected against<br>heavy seas|Water from heavy seas or water pro-<br>jected in powerful jets shall not enter<br>the enclosure in harmful quanties.|
|7|Protected against<br>the effects of im-<br>mersion|Ingress of water in a harmful quantity<br>shall not be possible when the enclo-<br>sure is immersed in water under stan-<br>dard conditions of pressure and time.|
|8|Protected against<br>submersion|No ingress of water.|
## **Resistance to climatic conditions acc. to IEC 68**
Open-type devices are climate-resistant in the constant climate according to IEC 68-2-3 (this is a climate with an ambient temperature of 40°C and an atmospheric humidity of 90 to 95%).
Enclosed devices are climate-resistant in an alternating climate according to IEC 68-2-30 (this is a moist alternating climate with a 24-hour cycle between climates with an ambient temperature of 25°C, and an atmospheric humidity of 95 to 100% and an ambient temperature of 40°C, and an atmospheric humidity of 90 to 96% in the presence of condensation during rises in temperature).
Data are valid up to an altitude of 2000m above sea level.
## **Short circuit protection**
Back up fuses should be used to protect contactors and starters against short circuits. For starters the device with the smaller admissible fuse at the main and at the control circuit (contactor or thermal overload) determines the fuse size.
After a short circuit devices have to be checked for correct operation. Disconnect power before proceeding with any work on the equipment!

## ■ **Rated currents of 3-phase motors (approx. figures for squirrel-cage motors)**
## **Minimum fuse size for protection of 3-phase motors**
The maximum size is determined by the requirements of the switchgear or overload relay.
The rated motor currents are for standard 1500 r.p.m. 3-phase enclosed ventilated and totally enclosed fan-cooled motors. D.O.L. starting: Maximum starting current 6 x rated motor current. Maximum starting time 5 s. Y/D starting: Maximum starting current 2 x rated motor current. Maximum starting time 15 s. Set overload relay in the phase lead to 0.58 x rated motor current. Rated fuse currents for Y/D starting are also valid for 3-phase motors with slip-ring motors. For higher rated currents, starting currents and/or longer starting times, larger fuses are required. Table is valid for “slow” and/or “gL” fuses (DIN VDE 0636).
## **For NH fuses with aM characteristics, fuses = rated current is selected.**

## **Minimum fuse size for protection of 3-phase motors**
The maximum size is determined by the requirements of the switchgear or overload relay.
The rated motor currents are for standard 1500 r.p.m. 3-phase enclosed ventilated and totally enclosed fan-cooled motors. D.O.L. starting: Maximum starting current 6 x rated motor current. Maximum starting time 5 s. Y/D starting: Maximum starting current 2 x rated motor current. Maximum starting time 15 s. Set overload relay in the phase lead to 0.58 x rated motor current. Rated fuse currents for Y/D starting are also valid for 3-phase motors with slip-ring motors. For higher rated currents, starting currents and/or longer starting times, larger fuses are required. Table is valid for “slow” and/or “gL” fuses (DIN VDE 0636).
## **For NH fuses with aM characteristics, fuses = rated current is selected.**
