To provide a circuit breaker capable of preventing insulation breakdown for secondary winding of a transformer and connector components, and capable of easily showing its connection condition, even though an open state is happened among secondary output when a connector is not completely connected and when any connector component is dislocated with vibrations, in the circuit breaker having a current detection function.
In the circuit breaker having the current detection function, a push-button switch is added so as to arbitrarily make a closed circuit among secondary winding, the push-button switch is opened and closed according to connection conditions of a connector section, and a link mechanism for showing the connection condition of the connector section is arranged on the surface of the circuit breaker.
