CFM3 series molded case circuit breaker is suitable for the circuit of AC 50Hz with rated insulation voltage 690V and rated voltage up to 690V with rated current up to 800A. It is mainly used to distribute electric energy and protect circuit and power supply equipment from overload, short circuit, and under-voltage. MCCB is intended for infrequent conversion and infrequent motor start in a circuit under normal conditions also provides protection against overload, short circuit, and under-voltage of the motor from damage.
