Claims (1)

[Scope of Claim for Utility Model Registration] (1) A box frame with an appropriate number of unit chambers spread over an appropriate number of stages and a general terminal chamber on the lower side, and a box frame in which a plurality of units are housed in parallel in the left and right direction within the unit chamber. The unit is equipped with a vertically long box-shaped unit that stores control equipment inside, and a hook-shaped handle that is pivotally attached to the upper front end of the unit via a support shaft. The lower part of the room is used as a horizontal busbar room, and the rear part is used as a wiring room, and a fixed load connector is installed in the upper part of the rear side of the room, and a 3-phase horizontal busbar is installed in the horizontal busbar room in the lower part in the front and back direction. Insulated wires are arranged in parallel and have one end connected to the fixed terminal of the fixed load connector in the rear wiring room and the other end connected to the terminal of the general terminal room. is pivotally connected to the unit chamber via a hinge, and a power connector is attached to the bottom surface of the unit so that it can be freely connected to and separated from the horizontal bus bar, and the hook-shaped handle connects the horizontal arm portion and the vertical arm portion. A handle is formed on the front of the front end of the horizontal arm and a front of the lower end of the vertical arm, and a movable handle is formed on the rear end of the horizontal arm so that it can be freely connected to and separated from the fixed load connector in the unit chamber. A control center characterized in that a load connector is attached. (2) As a means for pivotally connecting the unit to the unit chamber via a hinge, the tip of a hook fixed to the unit is rotatably fitted to a support shaft fixed to the unit chamber. A control center according to claim 1 of the utility model registration claim. (3) As a means for pivotally connecting the unit to the unit chamber via a hinge, a shaft is fixed to the tip of a hook fixed to the unit in a notch groove opening upwardly formed in a bearing plate fixed to the unit chamber. 2. The control center according to claim 1, wherein the control center is rotatably fitted.
