PROBLEM TO BE SOLVED: To provide a fitting structure to a device mounting plate, which is capable of attaching a circuit breaker like a plug-in type, and does not damage distribution lines, and does not need a tool when removed.SOLUTION: The fitting structure is a structure of a circuit breaker and mounting plate for mounting the circuit breaker to a device mounting plate such as a distribution switchboard. A claw part which regulates a motion in the perpendicular direction with respect to the mounting plate and is opened in either direction is provided on the mounting plate, and at the same time, a recessed portion opened in an opposite direction to the claw part on the circuit breaker corresponding to the claw part is provided. A locking lever which can alternatively select, with an external knob, projecting or not projecting from the bottom surface of the circuit breaker is provided on the circuit breaker, and at the same time, a fitting part of the locking lever is provided on the mounting plate. The circuit breaker where the locking lever is made to be in a state of not being projected from the bottom surface thereof is made to be placed on the mounting plate, and after the claw part of the mounting plate and the recessed portion are made to be fitted to each other, the locking lever is made to project from the bottom surface and slipping-off to the load side of the circuit breaker has been carried out. |
