Claims

[Scope of utility model registration request]

It has an electromagnet to which a circuit voltage is applied, and a movable member that is attracted to a reset position when a reference voltage is applied to the electromagnet, and the movable member is attracted when the circuit voltage falls below the reference value. In an undervoltage trip device for a circuit breaker, which is released from the electromagnet and moved to an operating position, and in response to the movement of the movable member, operates a trip bar of a trip device to quickly disconnect the circuit. ,
A lever whose one end is actuated by the movement of the movable member and whose other end can engage the trip bar, a lever spring that resets the lever, and a lever that is pressed by the movement of the trip bar after the trip position to reset the movable member. The lever is actuated against the lever spring by movement of the movable member to trip the trip bar, and the movement of the trip bar after the trip position presses the reset member to cause the movable member to trip. An undervoltage tripping device for a circuit or breaker, characterized in that when the lever is reset, the lever is reset by the lever spring.
