High-Performance 6-63A 6kA 10kA Industrial Air AC Miniature Circuit Breaker (MCB)

Short Description:

CJM13-63 Type Miniature circuit breakers (MCBs) ensure electrical safety in homes and similar situations, such as offices and other buildings as well as for industrial applications by protecting electrical installations against overloads and short circuits. Once a fault is detected, the miniature circuit breaker automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. Warranting reliability and safety for people and assets, MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection. normally the rated current is 1,2,3,4,6,10,16,20,25,32,40,50,63A and rated voltage is 230/400VAC. frequency is 50/60Hz. according to IEC60898/EN60898 standards.
