A molded case circuit breaker, abbreviated MCCB, is a type of electrical protection device that can be used for a wide range of voltages, and frequencies of both 50 Hz and 60 Hz. The main distinctions between molded-case and miniature circuit breaker are that the MCCB can have current ratings of up

Most people do know what miniature circuit breaker is, but they may not know how miniature circuit breaker works, and how they protects from short circuit and overload, as they don’t know miniature circuit breaker construction, which is exactly the basic for knowing more about miniature circuit br

Each phase of conductor at the Residual Current Circuit Breaker passes through the zero-sequence current transformer, and the secondary side of coil connects with the electromagnetic tripper. Under normal condition, the vector sum of each phase of current passing through zero-sequence current transf

With the circuit breaker is becoming increasingly popular, many industries can use the family can also be used. But the moulded case circuit breakers relates to personal safety, can’t casually buy. If the quality of circuit breaker does not pass, will have very serious consequences. What MCCB You sh
