PROBLEM TO BE SOLVED: To provide a switchgear where a surge generated in a main circuit does not shift from secondary wiring of a current transformer for meters and a transformer for meters to wiring of a control circuit.SOLUTION: The switchgear includes: a multi-relay 6, which is attached to a front door 2 of a box 1 containing a breaker 3, a current transformer 4 for meters and a transformer 5 for meters and which has the integrated functions of protection, measurement, display and operation; and auxiliary equipment 8 for control which is used in combination with the multi-relay. Wiring is separated by making the connection face 6b of wiring 7 for connecting the multi-relay and the auxiliary equipment different from the connection face 6a of wiring 10, 11 for connecting the current transformer for meters and the transformer for meters with the multi-relay, thereby suppressing a surge. |
