Claims

[Scope of utility model registration request]

It has a coil block connected to a zero-phase current transformer that detects the zero-phase displacement of the load current, a yoke made of a magnetic material fitted to the coil block, and a display button protruding from one side of the cover case. A display body is slidably held by the coil block and biased by a spring in the direction of protruding from the cover case, a plunger is fitted into the coil block and is attracted and driven by the excitation of the coil block, and a display body that responds to the plunger. The earth leakage release block is equipped with a tripping lever that operates the trip link and releases the display, and is connected to the trip link to a cover case above the earth leakage release block. In an earth leakage release device for a breaker, which has an operation handle that detects earth leakage and performs a trip operation to forcibly separate a fixed contact and a movable contact via an earth leakage removal block, the tripping operation causes a trip link. In the neutral state of the operating handle when activated, and the off state of the operating handle where the fixed contact and movable contact are separated, the display button of the display body is engaged with the lower part of the operating handle and stored in the cover case. A circuit breaker earth leakage release device comprising a reset bar protruding from a display body.
