## **S ecifications p** 

## ■ **Engineering data and Characteristics** 

## **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.

I The curve shows the mean operating current at an ambient temperature of 20°C starting from cold. II The tripping characteristic of electromagnetic overcurrent releases (short-circuit releases) The tripping characteristic of the inverse-time delayed overload releases apply for DC and AC with a frequency of 0 to 400 Hz. At operating temperature, the tripping times of the thermal releases are reduced to approximately 25 %. The characteristic shown here is a schematic representation of circuit-breakers for all ranges.

## **Descriptions** 

## **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-3P are actuated via a rocker operating mechanism and circuit-breakers J7MN-3R, J7MN-6R and J7MN-9R via a rotary operating mechanism. An electrical signal can be output, at all Circuit-breakers, via a signalling switch to indicate that the Circuitbreaker has tripped. 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 60947-2. 

## **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. 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. 

## **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 from being caused. 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 Manual Motor Starters. The current of the motor to be protected is set with the aid of the scale. 

## **Line protection** 

J7MN Circuit-breakers for motor protection are also suitable for line protection. The J7MN Circuit-breakers fulfil the isolation conditions of IEC 60 947-3 as well as the additional test conditions for circuitbreakers with isolation characteristics specified in IEC 60947-2. 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.
