Circuit Breaker > Molded Case Circuit Breaker | MCCB

Molded Case Circuit Breakers are able to cut off current automatically when the current exceeds the trip setting. Molded case refers to useing plastic insulators as device shell, used to isolate the conductor and the ground metal parts. Molded case circuit breakers typically contain thermal magnetic trip units, and large molded case circuit breakers are equipped with solid-state trip sensors. The tripping unit is divided into: thermal magnetic release and electronic release. There are several kinds of commonly used, rated current as following: 16 25 30 40 50 60 75 80 100 125 160 200 225 250 315 350 400 500 630A
