Abstract (en)

[origin: EP2261944A2] An electromagnetic device for instantaneous trip use in a circuit breaker includes: a coil; an insulation pipe, a fixed core, a movable core moving in the insulation pile by a magnetic flux generated by the coil to operate a trip device; a spring for biasing the movable core, a yoke whose one end is provided at the outside end of the fixed core, and the other end is provided on the side of the movable core; and a stator having a stator contact, and being a conductive plate jointed to an end of the coil, engaging the fixed core, and fixed to the yoke. The stator forms a current path between the stator contact and the joint section with the coil for current circulation in the direction same as the current flow to the coil.
