ことを特徴とする開閉器。 a bimetal plate with bimetal contacts formed thereon;
A switch equipped with a movable member having a movable contact that contacts and separates from a bimetal contact, and a trip mechanism that opens the bimetal contact and the movable contact by warping in the tripping direction due to heat generation of the bimetal plate when an overcurrent occurs. The switch is characterized in that it is provided with a stopper structure that prevents the bimetal plate from warping in the tripping direction after the trip mechanism is activated by the bimetal plate warping when an abnormal overcurrent occurs.
