Claims

[Scope of utility model registration request]

A zero-phase current transformer that detects leakage current flowing in an electric circuit, an amplifier that amplifies the secondary output of the zero-phase current transformer, and an electromagnetic device that operates in response to the output of the amplifier. The contact provided in the electric circuit can be opened and closed by operating a handle, and when the contact is closed, a latch is released by the operation of the electromagnetic device, and when the latch is released, the contact is opened. In the device, a contact plate is provided with one fixed end on the movable side of the contact and the other end as a free end to which the movable contact is fixed, and the movable contact is fixed to the closing side surface of the contact plate. A movable contact plate with one end fixed and one end fixed is provided in parallel, and a fixed contact piece that separates from the free end of the movable contact plate is provided, and the amplification device is connected to the amplifier via the fixed contact piece and the movable contact plate. and an earth leakage breaker that supplied power to the electromagnetic device.
