Product Details
Molded case circuit breakers (MCCBs) are a type of electrical protection device used in power distribution and control systems. MCCBs are designed to protect electrical equipment and circuits from overcurrents, which can result from short circuits, overload, or under-voltage . CMTM1 series moulded case circuit breaker is suitable for rated insulation voltage 400/415/660/690/800/1000V , AC50/60Hz, Rated voltage 690V and below . It has the feature of compact structure, small size, high breaking capacity, short electric arc, and complete internal and external accessories. The product conforms with the standard of IEC60947-2| Frame current Inm(A) | 400 | ||||
