  Indoor High Voltage Switchgear Used Earthing Switch

Technical Parameters for JN4-12Q Earthing Switches

The earthing switch is a main component in a metal armoured draw-out type, enclosed switchgear. It is suitable for AC 3-phase 50Hz power system at a rated voltage up to 12kV. There is a voltage display device in the switch. It is used for grounding when maintenance of a high voltage equipment for safety.
