Frequently Asked Questions

When should I install a voltage protector?

Voltage protectors are recommended where mains supply is unstable or where sensitive appliances such as refrigerators, air conditioners and electronics need protection from voltage fluctuations and phase-loss events.

Does the voltage protector reset automatically?

Yes — after the mains voltage returns to a safe range, the protector reconnects the load automatically after a configurable delay (typically 5–600s).

Do you have three-phase models with phase-loss protection?

Yes, our three-phase voltage protectors detect over/under voltage on each phase, plus phase loss and phase sequence errors.
