XGN17-12 medium voltage switchgear is mainly used as reception and distribution of power supply
of 3.6- 12KV, 3 Phase AC, 50Hz indoor system.It is specially applied to cases where frequent operations
are needed. The main switch applies ZN28A-12 segmental type vacuum circuit breaker with Cd10 electro
magnetic operational mechanics, CT8/CT19A (B) spring operational mechanics, ZN28-12 series integral
vacuum breaker (with CD17 Electromagnetic Operational mechanics, CT17/CT19 spring operational
mechanics) or applies ZN63-12(VS1) vacuum circuit breaker. Isolation switch applies GN30-10 rotating
style and GN22-10 high current isolation switch.
