Miniature circuit breaker  are terminal protection devices that are most widely used in electrical terminal distribution devices . The intelligent switching element used in the prepayment system automatically trips and keeps the MCB in a tripping state when the user owes time . After the user pays the fee , it automatically closes and resumes power consumption . Due to the need for integrated intelligent remote control of the circuit breaker , a remote control module needs to be added to the side of the miniature circuit breaker , and the remote control module needs to take power or sample from the incoming or outgoing terminal of the miniature circuit breaker . Most of the current use is to install the PCB circuit boards on the outside of the miniature circuit breaker . After the end cap is added , the lead wire is connected with the control mechanism , or the fixed lead wire is used inside the switch to connect to the control mechanism . This is troublesome to install . The overall integrity is not strong , the appearance is not uniform , and the production cost is high .
