PROBLEM TO BE SOLVED: To provide a fitting structure to a device fitting plate, capable of fitting a circuit breaker such as plug-in type circuit breaker, with no damage on wiring, with no tool required when dismounting.SOLUTION: A structure of a fitting plate and a circuit breaker is provided, in which a plug-in type circuit breaker in which a plug-in terminal bracket is provided on a power source side is fitted to a fitting plate such as a power distribution panel. A lock lever is provided on a load side of the circuit breaker, in which a finger hook part can alternatively select and hold protrusion or non-protrusion downward from a bottom surface of the circuit breaker. The fitting plate is provided with an engagement part for engaging with the lock lever. By operating the finger hook part, the lock lever is made to protrude from the bottom surface of the circuit breaker, for engagement with the engagement part of the fitting plate. Thus, action in the direction of taking the circuit breaker out of the bus bar is regulated, and the circuit breaker is fitted to the fitting plate. |
