PROBLEM TO BE SOLVED: To provide a mounting structure of a circuit breaker in which a circuit breaker of a plug-in type or the like can be mounted, damage to wiring is prevented and in the case of removal, any machine tool is not required.SOLUTION: A structure of a circuit breaker and a mounting plate for mounting a plug-in type circuit breaker to a mounting plate such as a distribution board including a bus bar is characterized in that, at a load side of the circuit breaker, a lock lever is provided capable of alternatively selecting and maintaining whether to protrude from a bottom face or not through an external knob and on the mounting plate, a fitting part of the lock lever is provided. When the circuit breaker placed on the mounting plate is slid toward the bus bar, the bus bar is inserted into a plug-in terminal fitting, and the lock lever protrudes from the bottom face of the circuit breaker and is fitted to the fitting part of the mounting plate. Thus, a motion in a direction of removing the circuit breaker from the bus bar is regulated and a state where the circuit breaker is mounted on the mounting plate is obtained. |
