Voltage Protector

Voltage Protector Manufacturer — Over & Under Voltage Protection

TPKELE voltage protectors monitor incoming mains and disconnect downstream loads when voltage moves outside safe limits. Single-phase and three-phase versions on DIN rail protect refrigerators, AC, motors and electronics from over-voltage, under-voltage and phase-loss events — a high-volume product for distributors serving regions with unstable grid quality.

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.
