Claims

[Scope of utility model registration request]

(1) A zero-sequence current transformer that detects the zero-sequence current of the main circuit, an amplifier that amplifies the secondary output of this zero-sequence current transformer, an electromagnetic device that drives the plunger forward by the output of this amplifier, and this In an earth leakage breaker equipped with an earth leakage display device that displays earth leakage in conjunction with the operation of the electromagnet device, and an opening/closing mechanism that controls energization and opening of the main circuit, the support body 1. A plate-shaped rod disposed at the tip of the plunger and having a locking portion at the middle lower part, a rod spring attached to the tip of the rod and biasing the plunger and rod in the return direction, and the support attached to the body,
The rod has a square hole through which the rod is inserted so as to be movable back and forth, and is provided with an indicator button that releases the engagement between the lower surface of the square hole and the locking portion when the rod moves forward, and the plunger and the rod move forward. 1. An earth leakage breaker characterized in that the tip of the rod pushes a trip bar of the opening/closing mechanism to open the opening/closing mechanism.

(2) The earth leakage breaker according to claim 1, wherein the support body is also used as a box housing an amplifier.
