Circuit Breaker Moulded case circuit breakeris suitable for wires with AC 50Hz (or 60Hz), rated working voltage of 660V(690V) and below, DC 250V and below, rated current of 12.5A-800A, to distribute electrical energy, and to work as un-frequent switch-on and switch-off under normal conditions, and carry out overload protection, short circuit protection and owe-voltage protection in wires and equipments. Those circuit breakers with rated full rank level current of 400A and below, also can work as unfrequent starting of rat cage type motor, carry out disjunction protection in the course of operation, and work as overload protection, short circuit protection and owe-voltage protection of motor. Circuit breaker accords with IEC60947-2, GB14048.2GB14048.4 and other standards.
