Claims

[Scope of claim for utility model registration] (1) Zero-phase current transformer that detects leakage current in the main circuit;
A tripping coil that is energized to open the switching contact of the main circuit when an output is generated in this zero-phase current transformer, and a tripping coil that is wound around the zero-phase current transformer and normally connected to the zero-phase current transformer through a test button. In an earth leakage or disconnection switch equipped with a test conductor connected to the main circuit on the load side of the current device, the test conductor is provided with a switch that opens when the switch contact is opened by the tripping coil. Electric leakage and disconnection characterized by: (2) In a release-type electromagnetic device equipped with a tripping coil that has a button holder for holding a release display button, a switch actuation arm is provided on the button holder, and the switch actuation arm opens and closes the opening/closing switch. An electric leakage or disconnection device according to claim 1 of the utility model registration claim, characterized in that:
