To provide a circuit breaker, comprising a terminal device, in which it is directly easily grasped which circuit breaker selects which conductor when selectively connecting the terminal device in the circuit breaker and an external conductor or even after connection, workability of switching or confirming the terminal device in the selection is improved and erroneous confirmation is unlikely to occur.
A circuit breaker has a substantially box-shaped body and comprises a terminal for receiving electricity on a surface of a side face of the body. Regarding a terminal part, a rotary shaft is provided substantially in the center of the body in a width direction, such that the terminal part is pivoted in a freely rotatable manner. Since the terminal is disposed at one side face side in a view from the rotary shaft, when the terminal part is rotated, a terminal position is continuously moved from the one side face side to another side face side. Regarding a moving direction of the terminal between connecting positions, the terminal is moved substantially in parallel with a front face in a planar view from a front face side, and disposed while changing the position.
