PROBLEM TO BE SOLVED: To provide a plug-in type molded case circuit breaker which uses a distribution board of a single phase three-wire system, which enables easy switching for 100 V or 200 V. SOLUTION: A movable terminal member 3 incorporating a terminal metal fitting 8 or a movable terminal metal fitting 21 for a master bar connection is made freely detachable from a circuit breaker body 1, or a movable terminal member 15 incorporating a terminal metal fitting 18 or a movable terminal metal fitting 25 for the master bar connection is attached to be freely rotatably to the circuit breaker body 1. It is possible to switch the connection with each master bar by changing the fitting position of the movable terminal member 3 or the movable terminal metal fitting 21 to the circuit breaker body 1, or the movable terminal member 15 or the movable terminal metal fitting 21. |
