Factory Manual Type Low Voltag Circuit Breaker Wcm9z 250A, 630A ODM OEM
WCM9Z series MCB is one of updated type MCCBs researched and developed by the company by using advanced design and manufacture technology internationally.
WCM6 sereis moulded case circuit breaker (MCCB for short) is the new type of product with top current limiting principal and manufacture technology in design, is tight in structure, total molularized, high breaking capacity, zero flashover. It applies at AC50Hz, rated operation voltage 690V and below, rated operation current upto 1250A for infrequent switch of line and infrequent start of motor. MCCB has overload, short circuit and under voltage protection device, to protect line and power evice from demage.
