Thermal Magnetic Miniature Circuit Breakers
## Introduction Choose the Right Weidmuller Miniature Current Breaker (MCB) (Always refer to the NEC before installing any device.)
When considering the UL 489 and UL 1077 Series MCBs, always assess the application for the following: voltage rating, Maximum interrupting capacity, continuous current rating, frequency, and atypical operating conditions (ambient temperature, moisture, vibration, altitude, installation or operation orientation, and field maintenance) ~~.~~ The MCBs are intended to protect the circuit cables as well as motors, generators and transformers, thyristors and silicon rectifiers ~~.~~ They also provide additional protection of computers and their peripheral equipment, industrial process control systems, telecommunications equipment and power supplies ~~.~~
## Ask the following:
- e ls the application an AC or DC circuit? Good news here, UL 489 and UL 1077 MCBs are rated for both AC and DC ~~.~~
- ¢ Is a branch or supplemental breaker needed for the application? Branch devices may be used in place of supplemental but not vise versa ~~.~~
- ¢ How many poles are needed for each circuit being protected? 3p ~~-~~ 3 phase no neutral, 2p ~~-~~ L, and Neutral, 1p ~~-~~ L, only ~~.~~
- e What are the functional requirements of the breaker? The UL 489 and UL 1077 are rail mountable, easy to visually inspect, switch manually (or remotely trip with shunt trip devices) and monitor using an auxiliary contact ~~.~~ Mechanically 20,000 cycles and electrically 6,000 cycles ~~.~~
- ¢ What is the wire size used? Can the breaker accept the wire sizes required? The UL 489 and UL 1077 are designed for <35mm2 ~~.~~
- ¢ Calculate and/or measure the normal current for the circuit and follow NEC guidelines ~~.~~ Match the breaker amps based on the normal current load ~~.~~ Weidmuller’s MCB’s run 1 to 63 amps (See Technical Data on page 4) ~~.~~
- ¢ Determine potential failure mode(s) ~~.~~ The MCB thermal magnetic devices are designed for interrupt short ~~-c~~ ircuit and overload events ~~.~~
- e What are the environmental factors: ambient temperature, moisture, vibration? Check to determine if there are unusual conditions in which the breaker must operate ~~.~~ The UL 489 and UL 1077 are specified to IP20, ~~-~~ 35°C ...70°C, and shock tested to IEC 60068- ~~2-2~~ 7 ~~.~~

¢ What is the interrupt capacity (IC)? ) \<br>Specify the breaker knowing the maximum fault current that ‘ =:<br>can be repeatedly interrupted without failure of the breaker .

Thermal Magnetic Miniature Circuit Breakers
Weidmuller MCB489 and MCB1077 Series breakers are UL tested and certified as current limiting protective devices ~~.~~ Current limiting circuit breakers provide a higher level of circuit protection than a typical zero point external breakers ~~.~~
## Ampere Rating
A rating of the amount of current a protective device will carry continuously without deteriorating or exceeding temperature rise limits ~~.~~ Arc The effect generated when electrical current bridges the air gap between two conductors that are not touching ~~.~~ Branch Circuit
The conductor and components following the last over ~~-~~ current . . . protective device protecting a load ~~.~~
oo, Circuit Breaker
A device designed to open and close a circuit by non-automatic means, and to open the circuit automatically on a pr ~~e-~~ determined overcurrent, without damage to itself when properly applied within its rating ~~.~~
Current Limiting A type of supplementary protector which limits the amount of damaging short circuit current ~~.~~ DIN ~~-R~~ ail A solidly mounted, rail-type device to which any number of circuit breakers can be mounted ~~.~~
## Double Pole
Term used to describe a breaker that draws power from two poles of a load center or similar device ~~.~~
## Frame
A component of a miniature circuit breaker. Its primary function is to provide a rigid, mechanically strong, insulated housing in which the other components are mounted.
## IEC
Abbreviation for International Electrotechnical Commission ~~.~~ This organization is associated with equipment used internationally.
IEC 60947 ~~-~~ 2 Current Limiting Circuit Breaker A circuit breaker with sufficiently short trip time to prevent the short circuit current from reaching the peak value which would otherwise be reached.
Interrupting Rating The highest current, at rated voltage, that a device is intended to interrupt under standard test conditions ~~.~~
Le ~~t-~~ through Current The maximum instantaneous or peak current which passes through a protective device ~~.~~ Load Center
A device; that delivers; electricity_ from a supply source to loads ;in light commercial or residential applications ~~.~~
## NEC
Abbreviation for National Electrical Code ~~.~~ A standard for applying electrical equipment in the United States ~~.~~
NEC240 ~~.~~ 2 Current Limiting A device that, when interrupting current in its current-limiting range, reduces the current flowing in the faulted circuit to a magnitude substantially less than that obtainable in the same circuit if the device were replaced with a solid conductor having comparable impedance ~~.~~ . . Operating Mechanism A component of a miniature circuit breaker. Its function is to provide . . ar the means of opening and closing the circuit ~~.~~ o P ive Devi vercurrent Protective Device A device such as a circuit breaker or fuse. In the event of an overload or short circuit, this device will quickly terminate power to the circuit ~~.~~ Overload (or Overcurrent) A condition in which current is in excess of the normal load being drawn ~~.~~ Short Circuit
An electrical fault created when two exposed conductors touch ~~.~~
## Single Pole
Term used to describe a breaker that draws power from one pole of a load center or similar device ~~.~~
## Supplementary Protector
A device similar in function to a miniature circuit breaker, but not UL approved as a circuit breaker ~~.~~ Used in conjunction with circuit breakers ~~.~~
## Thermal Magnetic
The predominant trip unit technology used in the domestic market ~~.~~ A bimetal and an electromagnet work together to provide overload and short circuit protection ~~.~~ UL AC GOHz Cycle UL defines an AC cycle as the potential energy of the wave form traveling from Zero ~~-t~~ o ~~-P~~ ositive amplitude, Positive ~~-~~ t ~~o-~~ Zero amplitude, Zero-to-Negative amplitude, Negative-to-Zero amplitude 60 times in one second ~~.~~ One cycle is completed every 16 ~~.~~ 6 milliseconds ~~.~~ oo. UL Breaker Current Limiting UL defines breaker current limitation as a breaker that interrupts and isolates a fault in less than half of an AC cycle ~~.~~ Half a cycle is completed in 8 ~~.~~ 3 milliseconds ~~.~~ : TheWithstandmaximum. Ratingcurrent that an unprotected electrical. component can sustain for a specific period of time without the occurrence of extensive damage ~~.~~
## Miniature Circuit Breaker (MCB)
A specific type of circuit breaker, used to switch and protect the lowest common distribution voltage in an electrical system ~~.~~ Generally used in a load center, panelboard or similar device ~~.~~
25
Thermal Magnetic Miniature Circuit Breakers
During normal operation and the MCB switch engaged, current flows in the line side terminal to a bimetallic strip, moving contact, fixed contact, current coil (magnetic trip coil) and out the load side terminal to complete a series path ~~.~~
The MCB enclosure housing is a molded plastic material. This provides mechanical strength and insulation from the components inside ~~.~~ The switching system consists of a fixed and a moving contact plate to which incoming and outgoing conductors are connected ~~.~~ The current carrying components are made up of various metallic compounds depending on the rating of the circuit breaker ~~.~~
The orange lever is used to manually engage/disengage the contact under normal ON/OFF conditions, as well as indicate status of the device. It also allows manual RESET of the latch after an overload or short circuit event ~~.~~
The thermal overload configuration for the slow rising current over time consists of a strip of bimetal (two dissimilar metals) ~~.~~ The rise in current causes a rise in temperature ~~.~~ The heat generated within the bimetal itself is enough to cause deflection due to thermal expansion of the dissimilar metals ~~.~~ This deflection further releases the trip latch mechanism and the contact faces separate ~~.~~
The magnetic tripping configuration for short circuit conditions consists of a system that allow fast rise time current (too fast for the bimetal) to separate the contact faces using a spring loaded plunger ~~.~~ The current carrying coil in this trip configuration moves the plunger when a strong magnetic field produced by the coils releasing the plunger engaging the trip latch mechanism ~~.~~
From the action of the fixed and moving contact faces separating in the event of an overload or short circuit situation, an electric arc in air is formed ~~.~~ The UC Series is designed to handle the arc interruption process where arc energy extraction and its cooling are provided by the arc runner and parallel arc splitter plates called the arc chute ~~.~~ These plates are held in position by the housing material. The operating mechanism consists of both magnetic tripping and thermal tripping arrangements ~~.~~

Thermal Magnetic Miniature Circuit Breakers
## ACDC Series D Curve Thermal Magnetic Tripping Characteristics vs K Curve
The K and UC Series D curve breakers are both designed for motor applications where ampacity rises quickly and momentarily during “star ~~t-~~ up” ~~.~~ Both curves can “ride through” the momentary inrush of current and prevent nuisance tripping while providing protection to the circuit ~~.~~
Both curves have almost identical tripping characteristics ~~.~~ The magnetic element tripping characteristics are identical between the two curves and the thermal element tripping characteristics have a slight variation ~~.~~

Thermal Magnetic Miniature Circuit Breakers
## D Curve
## Short Circuit. TrippingCharacteristics= ge ComparisonExample: 10 Amp K Curve Breaker and UC Series 10 Amp D Curve Breaker Short Circuit at 100 AmpsP Both breakers have an element that will trip between 10 and 14 times rated current ~~.~~ Both breakers will trip under a short circuit before ~~.~~ 01 seconds ~~.~~ And both breakers are guaranteed to trip no later than .01 seconds for any short circuit equal to 100 A or greater ~~.~~
## an eries ‘urve Summa "y Thermal Element Minimum Tripping
The UC Series D curve MCB will interrupt an overload at 2X rated current in 7 ~~.~~ 5s or greater ~~.~~ The K curve MCB will interrupt an overload at 2X rated current in 6 seconds or greater ~~.~~ This additional time allows a circuit more time to “ride through” high inrush at star ~~t-~~ up and prevent nuisance tripping ~~.~~
## Thermal Element Bandwidth
The K curve tripping bandwidth at 2X rated current is between 6 and 350 seconds ~~.~~ The UC Series D curve tripping bandwidth at 2X rated current is between 7 ~~.~~ 5 and 150 seconds ~~.~~ The differences between the bandwidths demonstrate calibration and quality control accuracy ~~.~~ The UC Series D curve breaker from Weidmuller has a much smaller tolerance bandwidth and requires a higher level of adjustment during manufacturing and quality control validation. Magnetic Element
The magnetic element of the K curve and UC Series D curve MCBs are identical. Both breakers interrupt a short circuit at 10X the rated current (or greater) in no later than ~~.~~ 01 seconds ~~.~~
