Circuit Breaker of Motor Protection

GSM8-32 range motor protection circuit breaker adopts modular structure, so accessories such as auxiliary contact terminals, alarming terminals, under voltage release, shunt release, etc. can be easily mounted onto it. It can offer overload, short circuit and three phase imbalance protection functions to three phase electric motors. Also, it is ideal electrical apparatus for infrequent starting, in-operation switching off of motors. It can additionally be used as an isolator. In order to allow customers feel secure in placing orders, we design and manufacture this range of circuit breaker in strict compliance with GB14048.2, GB14048.3 and GB14048.4 standards. This makes the products successfully certified by CCC and CE.
