KGN -12 Fixed Metal-clad Switchgear
Summary
KGN -12 fixed metal-clad switchgear(short for switchgear as below) applies to 3.6~12KV, 3 phase AC 50/60Hz network for receiving and distributing power energy and also for control, monitor and protection. It ca n be used in s ingle busbar, single busbar section system. It is manufactured accords to IEC62271-200& GB3906 3~35KV AC Metal Enclosed Switchgear, DL404 Order Specifi cation for Indoor AC HV Switchgear and so on. It has reliable prevention function against false operation.
