回路遮断器の電圧引外し装置。[Scope of Claim for Utility Model Registration] (1) An excitation coil, a bobbin around which the excitation coil is wound, an anvil and a plunger inserted into the through-hole of the bobbin, and the anvil fixed to one side and the other side. a voltage puller comprising: a yoke having a plunger through hole in the yoke and positioned relative to the excitation coil so as to be penetrated by the plunger and forming a magnetic path with the anvil and the plunger; and a return spring that resists the attractive force of the plunger. A voltage tripping device for a circuit breaker, wherein the plunger through-hole is punched, and the yoke is provided with a protrusion on the periphery of the through-hole that has an upright portion larger than the thickness of the yoke plate. (2) The voltage tripping device for a circuit breaker according to claim 1, wherein the protrusion also serves as a guide for the return spring.
