Zusammenfassung:The utility model relates to an electric power protection monitoring technology field, a circuit breaker heating circuit monitoring devices, it includes measurement and control device, a looks overload relay, B looks overload relay and C looks overload relay, the first terminal of A looks overload relay is connected with measurement and control device remote signalling common port electricity, a looks overload relay second terminal is connected with the first terminal of B looks overload relay electricity, B looks overload relay second terminal is connected with the first terminal of C looks overload relay electricity, a C looks overload relay second terminal and measurement and control device wiring end electricity is connected. The utility model has the advantages of reasonable and compact structure, through the overload relay that establishes ties in the heating circuit is personally experienced sth. Part of the body to the circuit breaker jar, start the action contact with overload relay and send the meas
