<P>PROBLEM TO BE SOLVED: To provide a fitting structure to an equipment fitting plate, capable of fitting a circuit breaker of, for example, plug-in type, with no damage on wiring, and with no tool required at the time of dismounting. <P>SOLUTION: The present invention is related to the structure between a circuit breaker and a fitting plate, for fitting the circuit breaker to an equipment fitting plate such as a distribution panel. The circuit breaker is provided with a recess part which regulates movement in the direction perpendicular to the fitting plate, with a tab opened to one direction provided to the fitting plate, and is opened in the direction opposite to the tab while corresponded to the tab. The circuit breaker is provided with a lock lever capable of selecting protrusion or non-protrusion from the bottom surface of the circuit breaker using an external knob. An engagement part for the lock lever is provided to the fitting plate. The circuit breaker which is in such a state as the lock lever does not protrude from the bottom surface is placed on the fitting plate. After the tab of the fitting plate is engaged with the recess part, the lock lever is caused to protrude from the bottom surface, for preventing the circuit breaker from coming off onto a load side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
