Molded Case Circuit Breaker 63A 4P

Product pain point: Resolving faults in branch circuits

In a three-phase four-wire (380V/220V) distribution system, motor blockage can lead to overload, short circuits between lines can cause tripping, or neutral line faults can bring about difficult-to-detect hidden dangers. Ordinary switchgear often cannot cope with the situation of continuous large current.

The molded case circuit breaker 63A 4P was developed precisely to address this issue. This product features a key node protection function that lies between miniature circuit breakers and large frame circuit breakers, providing a solution for circuit on-off and protection.
