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 latch whose one end is actuated by movement of the movable member, a latch spring which resets the latch, and a lever whose one end is removably engaged with the other end of the latch and whose other end is engageable with the trip bar. , a lever spring that biases the lever in the direction in which the trip bar trips, and a reset lever that is actuated by the movement of the trip bar after the trip position and resets the lever against the lever spring; When the latch is actuated against the latch spring, the lever disengaged from the latch is actuated by the lever spring to trip the trip bar, and movement of the trip bar after the trip position actuates the reset lever. 1. An undervoltage tripping device for a circuit or breaker, characterized in that when the lever is reset against the lever spring, the latch that has come off the lever is reset by the latch spring.
