<p>PROBLEM TO BE SOLVED: To provide a metal-enclosed switchgear that requires only a small setting space by downsizing both dimensions of the width and depth of the device, without deteriorating the efficiency of cable-connecting work. SOLUTION: Load-side conductors 5 are individually connected to a plurality of buses 2 via each switch part 6 of breakers 3, and these devices are stored inside a metal frame panel 11. Each switch part 6 making up the breaker 3 is arranged parallel in the depthwise direction. In a state of facing the back- surface of the metal frame panel 11, power-side terminals 8 connected to the buses 2 and load-side terminals 9 connected to the load-side conductors 5 are arranged straight, vertically in the heightwise direction and shifted step by step in the depthwise direction, in such a way that the distances between the power-side terminals 8 and the load-side terminals 9 with the switch part 6 at the center gradually become shorter.</p> |
