や断器。 An electromagnet for overcurrent detection, a plunger of the electromagnet having a flange at its protruding tip, and a hole into which the plunger can be inserted, and which can be engaged with the flange when the plunger is inserted into the hole. In a circuit switch or disconnector having a movable contact, the movable contact is made smaller in the width direction of the movable contact so that the collar of the plunger does not pass through the hole, and the hole is narrowed from the center in the width direction to the 1. A circuit breaker, characterized in that the hole is eccentrically provided on the side of the movable contact, and an insertion opening for inserting the plunger from the side of the movable contact is provided on the eccentric side of the hole.
