Abstract:
The purpose of the present disclosure is to quickly extinguish an arc when an arc occurs. A circuit breaker (100) comprises a fixed terminal (1), a movable contactor (3), a moving mechanism, an igniter (51), and an accommodation chamber (70). The fixed terminal (1) has a fixed contact (11). The movable contactor (3) has a movable contact (31) that is connected to the fixed contact (11). The moving mechanism moves the movable contactor (3) from a closed position where the movable contact (31) is connected to the fixed contact (11) to an open position where the movable contact (31) is separated from the fixed contact (11). The igniter (51) generates a gas via combustion. The accommodation chamber (70) accommodates the fixed contact (11) and the movable contactor (3). In the circuit breaker (100), the gas is introduced into the accommodation chamber (70).
