Claims

[Scope of utility model registration request]

In low-voltage distribution switchgear that includes low-voltage switching means for each of multiple loads fed from a common bus bar and is installed in parallel in a common panel so that multiple units can be drawn out, it is installed in an insulated molded case that can be handled as a unit. A low-voltage opening/closing mechanism and a protection circuit device for each of the loads are housed, and a connecting terminal rod that can be inserted and connected to the common bus bar on the panel side is planted on the rear side of the molded case, and a connecting terminal rod that can be inserted and connected to the common bus bar on the panel side is installed in the back side of the molded case. A plurality of vertically elongated recesses are bored, and the mold case can be freely inserted and removed by sliding the recesses into rod-shaped guide members that protrude toward the front side of the plurality of boards from a mounting rack provided on the board side. An integrated drawer-type low-voltage power distribution switchgear, characterized in that, at the same time, the connecting portion of the terminal bar can be inserted and connected to a common bus bar on the panel side in a freely insertable and detachable manner.
