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.
