LEL12-2R-40864-2R2-G2 Circuit Protection

Circuit Breakers

A circuit breaker is a protective device equipped in an electrical circuit, that monitors the flow of electricity in that circuit, and if it detects an overload or a short-circuit, it will mechanically trip the circuit and cut off the power. Circuit breakers react very quickly to faulted current and thus providing a better protection against over-voltage than fuses.

LEL12-2R-40864-2R2-G2 is a type of circuit breaker produced by MEGB Corporation. It is generally used in the low voltage power distribution, combined with low-voltage switchgear. It is suitable for power distribution in residential areas, commercial zones, motion control, air conditioning systems, elevators and other areas. It is a three-pole molded case circuit breaker, with thermal-magnetic trips rated from 16A to 40A.

Application Field of LEL12-2R-40864-2R2-G2 Circuit Breaker:

LEL12-2R-40864-2R2-G2 circuit breaker can be used for overload and short-circuit protection of residential areas, commercial zones, motion control systems, air conditioning systems, elevators and other equipment. Its most common application is used to protect circuits that have a maximum voltage rating of 277/480 V for AC or 125V for DC.

Working Principle of LEL12-2R-40864-2R2-G2 Circuit Breaker:

The trip unit of LEL12-2R-40864-2R2-G2 circuit breaker contains two types of protection: thermomagnetic protection and electronic protection. Thermomagnetic protection is responsible for sensing the excess current flowing through the circuit. When the current exceeds the threshold level set on the trip unit, a thermal trip element will sense the excess current and will send a signal to the breaker\'s mechanism to trip it. The Electronic protection provides protection against the excess voltage in the circuit. It will measure the voltage in the circuit and will send the signal to the breaker\'s mechanism to trip the breaker when it exceeds the pre-set value.

This type of circuit breaker is also designed with advanced circuit breaker features such as dual-element operating mechanism, calibration adjustment, terminal markings for easy wiring, and visual circuit breaker status indications for easy identification.

Conclusion:

LEL12-2R-40864-2R2-G2 circuit breaker is a three-pole molded case circuit breaker, designed with dual-element high breaking and interrupting capacity, thermal-magnetic trips from 16A to 40A. It is used in low voltage power distribution with low-voltage switchgear and its most common application is to protect circuits with maximum voltage ratings of 277/480V for AC or 125V for DC. Its trip unit contains two types of protection: thermomagnetic and electronic protection.
