装置。 An electromagnetic tripping coil in which a plunger is inserted is connected in series with a bimetal, and when a large current flows, the plunger opens the switching contact, and when an overload current flows, the bimetal deforms to open the switching contact via the switching mechanism. In such a circuit breaker tripping device, a bypass circuit having a fixed contact and a movable contact that can be opened and closed with respect to the fixed contact is connected in parallel to the bimetal, and when the plunger is tripped, the bypass circuit is connected in parallel to the bimetal. A tripping device for a circuit or breaker, characterized in that the movable contact closes with respect to a fixed contact.
