Interlock device of draw-out type circuit breaker, draw-out type circuit breaker, and power distribution board

A draw-out type circuit breaker having the interlock device, comprising:

• a tripping button that is linked to a tripping mechanism of the draw-out type circuit breaker;
• an interlock rod that is placed so as to be movable up and down;
• a main contact that closes and opens a main circuit;
• a driving unit that drives the main contact;
• a main circuit energizing part that allows a main circuit current to flow;
• a connecting part that enables the main circuit energizing part and the main circuit portion in a power distribution board to be removably connected to each other;
• and
• a moving device that moves the draw-out type circuit breaker;
• wherein the tripping button mechanically prevents an operation to raise the interlock rod unless the tripping button is operated to place the draw-out type circuit breaker in an open state, so a power distribution board floor surface or a member fixed on the power distribution board floor surface and the interlock rod mechanically interfere with each other and the draw-out type circuit breaker is fixed at a predetermined position in the power distribution board;
• and
• wherein the interlock device fixes the draw-out type circuit breaker accommodated in the power distribution board at a predetermined position.

• wherein the interlock rod has an interlock pin, which is integrally formed with the interlock rod, by which the interlock rod is moved to a fixed position or a movable position for the draw-out type circuit breaker;
• and
• wherein the interlock device fixes the draw-out type circuit breaker accommodated in the power distribution board at a predetermined position, and the tripping button, the interlock rod, and the interlock pin are placed on the front of the draw-out type circuit breaker.
