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.
- Automatic disconnect on over-voltage and under-voltage
- Adjustable trip thresholds and reconnection delay
- Single-phase and three-phase DIN-rail models

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.
