Product Description

 

Product Description

General

WCM4(E) series moulded case circuit breaker (MCCB for short) is one of new type circuit breaker developed based on international advanced technology. The related insulation voltage is 1000V, applied to circuit of AC50Hz  or (60Hz), rated operation voltage 400V and below, rated operation current from 15A to 1600A for distributing electric energy. It is used for infrequent closing and breaking under normal circumstance to make protection at overload, under-voltage at lines and equipments. The circuit breaker of frame size rated current under 400A can also protect the squirrel-cage motor of infrequent start, breaking at running, overload, short circuit and under-voltage.

The product meets standards of GB 14048.2 and IEC 60947-2.
