The device installed in a housing of a breaker comprises a driving member, a limiting member, a linkage member, and a tripping mechanism. One end of the linkage member is concentrically hinged to a round hole of the driving member, and the other end is concentrically hinged to a trip through hole of the tripping mechanism. An inclined clamp groove surface of the limiting member oppositely and parallelly contacts with a concave surface of a contact support in the tripping mechanism, a gap left between the two surfaces. A cylindrical boss of the limiting member is tangent to a circular notch of a positioning shaft. The tripping mechanism mainly comprises the contact support, a lever, a trip and a lock.
