Molded Case Circuit Breaker

QJM1-63~630(CM1) series moulded case circuit breaker, incorporated with international, advanced technology, the series are divided into such four types as C type(basic capacity) M type (standard capacity), H type (higher capacity) and L type (current limiting). The item is ideal defender due to its small volume, big short circuit capacity and short electrical arc, vibration resistance and so on, it is an ideal products of land and ship. This product conforms to standard IEC947-2.

QJM1L series leakage circuit breaker is is a new type product developed and manufactured by adopting international advanced technology, compacted structure, small volume as the QJM1 MCCB, and also can install for a series. Its high circuit break capacity is the best product for the power supply system. It suitable for exchange of 50Hz, rated working voltage to 400V, rated current to 400A(630A) of the lines used for over-current protection circuit, also can be used to prevent the fire danger caused by the damage to equipment's insulation and earth fault currents. This product work as unfrequent conversion and unfrequent start. Circuit breaker has overload protection, short circuit protection as well as owe-voltage protection functions, can prevent wires and electric source equipments from being damaged. And it also can adjust the rated opperation current and time extending. The product conforms to the GB14048.2, GB6829-95.
