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.WESTHOMES ELECTRICS GROUP(L.L.C),A professional supplier of power transmission and distribution equipment, is engaged in the solutions and relative equipment for power transmission and distribution system of civil, commercial,industrial and construction uses, as well as the full range of service for endplants to mansions, infrastructure facilities and industrial fields.
