Description: molded case circuit breaker in electric appliance switch factory, www.jiandq.com
Molded case circuit breaker automatically interrupts the current flowing through it when the current exceeds the trip rating. Molded case refers to the use of the plastic insulator as the outer shell of the device, used to insulate the conductor and grounding metal part. Molded case circuit breakers usually contain thermal magnetic trip unit, and the types of molded case circuit breaker can be equipped with solid state trip sensors. The trip unit is divided into: thermal magnetic release and electronic tripping device.
