    Factory Cheap CEJIA Moulded Case Circuit Breaker Residual Current Operated CJMM1-125M Plug in Front of Board with CE

    Short Description:

    Application

    CJMM1 series moulded case circuit breaker(hereinafter referred to as circuit breaker) is pplicable for AC 50/60HZ power distribution network circuit with rated insulation voltage of 800V, rated operation voltage of 690V and rated operation current from 10A to 630A, it’s used to distribute power and prevent circuit and power supply equipment from damage due to overload, short circuit, under voltage and other faults, it’s also used for infrequent start of motor as well as overload, short circuit and under voltage protection.This circuit breaker owns advantages of small volume, high breaking capacity, short arcing (or noarcing)etc, it can be equipped with accessories like alarm contact, shunt release, auxiliary contact etc, it’s an ideal product for user. The residual current circuit breaker can either be vertically installed (vertical installation) or be horizontally installed (horizontal installation) The product is in accordance with the standards of IEC60947-2 and Gb140482

    What is MCCB?

    MCCB is shorthand for Moulded Case Circuit Breaker. When the total current surpasses the limitation of a micro fuse box, the user employs it as just another sort of overcurrent protection device. The MCCB protects from overvoltages as well as fault current failures, as well as shifting the circuits.

    Users may utilize it even in household applications for more outstanding current ratings and fault occurs levels. Users use MCCBs in commercial processes because of their average comprehensive ratings and high breakdown capacity. MCCBs can also safeguard capacitor banks, generators, and the distribution of main electric feeders. When an application requires discriminatory practices, customizable overloading settings, or ground-fault security, it provides suitable protection.Our pursuit and enterprise aim would be to “Always fulfill our buyer requirements”.
