Purpose:

 

The GSM8-32 and GSM8-80 series motor protection circuit breakers have the following purposes:

 

The GSM8-32 series motor protection circuit breaker is mainly used in circuits with AC 50Hz/60Hz, rated working voltage up to 690V, and rated working current of 0.1A~32A. It is used for overload, short circuit, and three-phase unbalance protection of three-phase motors, as well as for breaking during infrequent starting and operation. It can also be used as an isolator.

 

The GSM ⁸ -80 series motor protection circuit breaker is mainly used in circuits with AC 50H2/60Hz, rated working voltage up to 690V, and rated working current of 25A~80A. It is used for overload, short circuit, and three-phase unbalance protection of three-phase motors, as well as for infrequent starting and operation disconnection. It can also be used as an isolator.

GSM8 series accessories: expanding the number of auxiliary contacts, providing auxiliary signals, real-time monitoring, and connecting or disconnecting control circuits.
