THE TRIP DEVICE OF EARTH LEAKAGE CIRCUIT BRAKER

A trip device of an earth leakage circuit breaker comprises: a coil installed inside a main body; a permanent magnet installed on the lower end of the coil to generate magnetism; a plunger shaft installed through the main body, the permanent magnet, and the coil to be lifted up and down by suction or suction release and having an earth leakage display button installed on the upper end thereof; a guide hole vertically formed through the center of main body, the coil, and the permanent magnet and having a first spiral part formed on the inner peripheral surface thereof to have a vertical length; a movable core coupled to the outside of the plunger shaft, having a second spiral part formed on the outer peripheral surface thereof to be correspondingly combined with the first spiral part of the guide hole, and lifted up and down with the plunger shaft by horizontal rotation; and a fixed core fixed under the movable core to be spaced apart from the movable core and sucked or released from the movable core.
