  • High Voltage Earthing Switch

    High Voltage Earthing Switch

    SanGao high quality High Voltage earthing Switch is also called earthing switch. Earthing switch and earthing switch are used interchangeably. It is a protective device included in switchgear components such as circuit breakers and isolators. When the circuit breaker is removed and shaken out, the earthing switch automatically grounds the busbar section close to the circuit breaker. For isolators, the earthing switch contacts the busbar when the isolator isolates the circuit, releasing any charge that may have accumulated there.
