WCM3 series moulded case circuit breaker (MCCB for short), the main technical performance of which can reach to the international level, it has features of tight in structure, small in volume, high in short circuit breaking capacity, no flashover, modular installation of internal anciliary device, using terminal shield for protection, and beautiful enhancing apperance by using different colors of base and cover.

The MCCB is applied to lines of AC50Hz (or 60Hz), rated insulation voltage 690V, rated operation voltage upto 660V(690V), DC250V and below, rated current 12.5A to 1600A for power distribution, to close and break infrequentyly under normal condition to protect overload, short circuit and under under voltage at lines and equipments.

MCCBof rated frame level current 400A and below cna be infrequent starting of squirrel cage motor, to make protection when operation interruption, overload, short circuit and under voltage of the motor.
