Minimum Oil Circuit Breakers | MOCB

What is Minimum Oil Circuit Breakers? These minimum oil circuit breakers utilise oil as the interrupting media. However, unlike bulk oil circuit breakers, these designs place the interrupting units in insulating chambers at live potential. This feature of the design of MOCBs reduces the requirement of oil, and these breakers are therefore known as MOCBs. Minimum … Read more
