Miniature Circuit Breaker (MCB) CJM6-32

CJM6-32 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. It also can be used for non-frequent on-and-off switch operations under normal circumstances.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. The rated current is 6,10,16,20,32A and rated voltage is 230VAC. frequency is 50/60Hz. according to IEC/EN60947-2 standards.
