Moulded Case Circuit Breaker (HKKMS-1003P)
Moulded Case Circuit Breaker (HKKMS-1003P)

Product Description

HKKM-S moulded case circuit breaker is one of the most advanced type breakers in the world, which adopts international advanced design and manufacture technology. They are suitable for short circuit and overload protection in circuit of AC 690V 50/60Hz, rated current from 12.5A to 1600A. It takes protect effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage.
