    Abstract: A circuit interrupter includes: a first fixed terminal including a first fixed contact; a movable contactor which is formed as a separate part from the first fixed terminal and includes a first movable contact; a holding unit configured to hold the movable contactor so that the first movable contact is connected to the first fixed contact; and a squib configured to generate gas by combustion. In the circuit interrupter, pressure of the gas generated by the squib causes movement of the movable contactor in a direction away from the first fixed terminal so that the first movable contact is separated from the first fixed contact.

    Abstract: This breaker device includes: a casing; an igniter configured to generate gas; a pusher located inside the casing and positioned below the igniter; a conductor including a separating portion positioned below the pusher; and an elastic member disposed to be positioned between the casing and the pusher to press the outer side surface of the pusher. In the state where the pusher is stationary after the pusher moves the separating portion downward under the pressure of the gas generated by the igniter, the pusher is located at a level below the elastic member, and the inner surface of the elastic member overlaps the pusher as viewed from above.

    Abstract: A circuit interrupter includes a fixed terminal, a movable contactor, a moving mechanism, a squib, and accommodation. The fixed terminal includes a fixed contact. The movable contactor includes a movable contact connected to the fixed contact. The moving mechanism is configured to move the movable contactor from a closed position where the movable contact is connected to the fixed contact to an open position where the movable contact is separated from the fixed contact. The squib is configured to generate gas by combustion. The accommodation is for accommodating the fixed contact and the movable contactor. In the circuit interrupter, the gas is introduced into the accommodation.
