Claims

[Scope of utility model registration request]

A U-shaped frame that is attached to the panel surface and holds the circuit breaker; a cover that is attached to the frame and has a hole that covers the surface of the circuit breaker and projects its handle; and a back surface that is attached to the frame. A circuit breaker having a plug-in terminal, which slides on the surface of the circuit breaker,
a plate having a protrusion that engages with the handle portion and a notch and a mounting hole in a portion extending from the side thereof; a plunger mounted by sandwiching the frame in the mounting hole of the plate; and the plunger. an opening/closing plate provided at the lower part of the panel mounting portion of the frame that opens and closes when the frame moves; and a leaf spring that locks the notch of the plate on the cover;
When the circuit breaker is in the ON state, the protrusion is pushed out by the handle of the circuit breaker and the plate retreats, and the plate spring of the cover engages with the notch in the retreated plate, and the plunger holds the opening/closing plate in the frame. It opens to the outside to make it impossible to connect or disconnect the circuit breaker and plug-in terminal, and in the OFF state, the protrusion can be inserted by reversing the handle, the plate moves forward, and the plunger also moves to close the opening/closing plate. An interlock device for a circuit breaker, characterized in that the circuit breaker and the plug-in terminal can be attached and detached using the same method.
