■ Overview
■ XGN2-12 box-type fixed metal enclosed switchgear (hereinafter referred to as Switchgear), mainly for 3.6,7.2,12 KVthree-phase AC 50Hz indoor system as receiving and distributionof electric energy use, especially suitable for frequent operationoccasions. The switch cabinet in line with international standards,national standards GB3906 and IEC298, and has a strict "Five Anti" lockout feature.
The main switch using ZN28-12 Series Integral vacuum breaker(with the electromagnetic actuator with CD17 CT19 spring mechanism). Also can be used ZN28A-12 series vacuum circuit breaker points mounted with solenoid actuator with CD17 CT19spring mechanism. ZN63-12 (VS1) circuit breaker, disconnecting switch type using GN30-10 GN22-10 and the rotary-currentisolation switch.
