HT Changeover Switches

APC off-load Motorized isolator switch with an earthing mechanism is specifically designed for HT capacitor bank operation and high-voltage electrical systems for the purpose of connecting and disconnecting HT capacitor bank after used isolating sections of capacitor bank for the maintenance or repair. Isolators are typically used to ensure that electrical equipment can be safely worked on without risk of electric shock or other damages.

Earthing mechanism – The earth switch, sometimes called an earthing switch, is a mechanism used to connect the isolated HT capacitor bank to earth (ground), By grounding the isolated capacitor bank and residual electrical charge is safely dissipated, further ensuring the safety of personnel working on the system.
