Molded Case Circuit Breakers (MCCBs) refer to breakers where in the tripping mechanism is fitted in a molded frame and the breaker is used for rugged industrial use. These circuit breakers generally have higher breaking capacities as compared to MCBs and can handle larger amperes. Also, these breakers have features to provide extra protection from Short Circuits, Ground Faults and Overload protection.
The other low voltage circuit breaker types are : Miniature Circuit Breakers, Motor Protection Circuit Breakers, Earth Leakage Circuit Breaker, and Air Circuit Breaker. (more…)
