Product DescriptionCJM2-63-1 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.Construction and Feature·High short-short capacity
