Gn22-12 (c) disconnector is suitable for indoor equipment with three-phase AC 50Hz and rated voltage 12kV. It is used to connect, cut off or switch the line of high voltage equipment when there is voltage and no load
The GN22 switch is used to isolate the disconnect between the high voltage maintenance equipment and the electrical equipment for maintenance. The isolation switch is equipped with a circuit breaker, which needs to be reversed to change the system operation connection. GN22 is used to turn on or off small current circuits.
