PROBLEM TO BE SOLVED: To obtain a metal closing type switch gear capable of easily performing extension work and configuring many feeder circuits with little space.SOLUTION: A metal closing type switch gear includes: a power incoming panel 5 that has a power receiving side breaker 23 and an instrument transformer 13, and receives electric power; a feeder panel 6 that has feeder side breakers 10, 11, 18, a current transformer 13, and a zero-phase-sequence current transformer 17, and draws out an outside line for load supply; and a bus line communication panel 7 that has a bus line communication breaker 38 and separates a main bus line 3 for each circuit. Each of the power incoming panel 5, feeder panel 6, and bus line communication panel 7 alone can install a feeder unit 2 that configures a feeder circuit in a panel body unit 1 having a power distribution installation function. Each unit is accommodated in a separate housing, vertically arranged and installed, and detachably configured. |
