Claims

[Scope of Claim for Utility Model Registration] (1) In a wheeled circuit breaker that can be manually pulled out and inserted between a predetermined connection position and a disconnection position in a switchboard, approximately at the center of the front edge of the lower surface of the frame bottom plate. A fixed fulcrum pin and approximately 1
It is equipped with an approximately L-shaped operation lever that is rotatably supported by 80 degrees, and a guide mechanism consisting of a guide pin and a guide groove arranged between the end of the lever opposite to the pivot support and the floor surface. A circuit breaker characterized in that the circuit breaker is configured so that it can be moved back and forth by rotating 180 degrees. (2) A claim for utility model registration comprising a guide pin provided at one end of the operating lever, and a guide plate facing the guide pin, formed to be able to engage with and disengage from the guide pin, and fixed to the floor of the switchboard. The circuit breaker according to paragraph 1. (3) The circuit breaker according to claim 1, wherein a guide pin is provided upright on the floor of the switchboard, and an arcuate guide groove that engages with the guide pin is provided at the end of the L-shaped operating lever. (4) The circuit breaker according to any one of claims 1 to 3, which is provided with a stopper for the operating lever at the front and rear of the frame bottom plate.
