器。[Claims for Utility Model Registration] A zero-phase current transformer that detects leakage current in the main circuit, a tripping coil that is energized to open the switching contacts of the main circuit when an output is generated in the zero-phase current transformer, and an earth leakage breaker equipped with a sensitivity switching switch connected to the zero-phase current transformer, wherein the zero-phase current transformer is built into the base of the circuit breaker case, and the electromagnetic tripping circuit breaker has the tripping coil. A device is placed on the base using a mounting frame, the sensitivity selector switch is installed on the electromagnetic tripping device, and a cover of the circuit breaker case is placed over this, wherein a guide is provided on the inner surface of the mounting frame. and the lead wire of the sensitivity changeover switch inserted between the mounting frame and the tripping coil is bent back to the back side of the tripping coil by the guide and routed into the base. Characteristic earth leakage breaker.
