XGN2-12 Box type fixed metal enclosed switchgear
■ summary
XGN2-12 box type fixed metal enclosed switchgear (hereinafter referred to as switchgear) is mainly used for receiving and distributing electric energy in 3.6, 7.2 and 12KV three-phase AC 50Hz indoor systems, especially suitable for occasions with frequent operations. The switch cabinet meets the national standard GB3906 and all standards IEC298, and has a tight "five prevention" locking function.
The main switch adopts ZN28-12 series integral vacuum circuit breaker (equipped with CD17 electromagnetic operating mechanism CT19 spring operating mechanism). The ZN28A-12 series split mounted vacuum circuit breaker can also be used, with CD17 electromagnetic operating mechanism CT19 spring operating mechanism. For ZN63-12 (VS1) circuit breaker, the disconnector adopts GN30-10 rotary type and GN22-10 high current disconnectors.
