足電圧引外し装置。 An electromagnet to which a circuit voltage is applied, a plunger that is attracted and held by the electromagnet when the circuit voltage is equal to or higher than a reference voltage and released from holding when the circuit voltage falls below a reference value, and a frame with a standby position and an operating position. an actuating lever provided to reciprocate and rotate between the two; a lever spring that biases the actuating lever to rotate toward the operating position; an engaging portion which is movably provided and is rotated to a set position with the plunger being attracted and held, and engages one end of the actuating lever to restrict the actuating lever to a standby position against the lever spring; at the other end, and when the plunger is released from the electromagnet to allow the latch to rotate in one direction from the set position, the actuating lever moves from the engaging portion of the latch to the lever. a trip can that is disengaged by a biasing force of a spring and moved to a trip position based on an operation in which the operating lever rotates from a standby position to an operating position, thereby shifting the circuit breaker main body to a breaking state; and the frame; a reset lever provided so as to be able to rotate in conjunction with the movement of the plunger; and a reset lever that is moved in conjunction with the movement of the circuit breaker main body to the disconnection state to rotate the reset lever in one direction. A trip bar that moves the plunger to a position where it can be attracted to the electromagnet again by moving the plunger, the reset lever, and the actuating lever are connected to each other, and when the reset lever is rotated in one direction, the actuating lever is An undervoltage tripping device for a circuit breaker, comprising a linkage mechanism for returning and rotating against a lever spring.
