The GN30-12 indoor disconnector (hereinafter referred to as the disconnector) is a rotary switch of 12kV rated voltage, three-phase AC 50Hz for indoor use. This isolator switch is specially designed for XGN2-12, XGN66-12, HXGN-12 and other MV switchgears. The function of the disconnector is to make and break currents in the presence of no-load voltage, enabling the circuit breaker and the main bus to be isolated and grounded to ensure safe maintenance and reduce risks of accidents.
