New Type CJRV-32X MPCB 25-32A Motor Protection Circuit Breaker

Short Description:

The CJRV series AC Motor protection circuit breaker is suitable for circuits with AC voltage up to 690V and current up to 80A. lt is used for overload, phase failure,short circuit protection, and infrequent starting control of three-phase squirrel cage asynchronous motors. It can beused for distribution line protection and infrequent load switching, and can also be used as an isolator.
