Molded Case Circuit Breakers (MCCB) are applied to power distribution network of AC50/60Hz, rated operational voltage up to 690V, rated current up to 2000A.

■ It is mainly used to distributing electric energy and protecting circuit and power-supply device against the faults of overload, short-circuit and under-voltage;

■ And it also can work for transferring circuit and starting motor unfrequently;

■ MCCB has protect functions of overload long time-delay inverse time limit, short-circuit short-time delay inverse time limit, short-circuit short-time constant time-lag, short-circuit instantaneous and under-voltage;

■ The products have advantages of small volume, high breaking capacity, short-arc, accessory easy install, anti-vibration, conform to standard of IEC60497-2;
