CEM3 Moulded Case Circuit Breaker-Moulded Case Circuit Breaker-CEA Group International Co., Ltd

◆Application

CEM3 series moulded case circuit breaker is one of the most advanced breakers in the world. Which adopts international advanced design and manufacture technology. They are suitable for short circuit and overload protection for circuit of AC 690V 50/60Hz, rated current from 12.5A to 630A. It takes protective effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and undervoltage.
