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 opened, a latch is released by the operation of the electromagnetic device, and when the latch is released, the contact is opened. In the device, the electromagnet device is provided with a fixed core in one center hole provided in the coil frame, a movable core in the other, and a return spring interposed between the fixed core and the movable core in the hole. Furthermore, an actuating plate for transmitting motion to the opening/closing mechanism is fixed to the movable iron core, and an earth leakage tripping coil and an external tripping coil are separately wound around the coil frame.
