Voltage Protector

PN2-VAK Voltage Protector

TPKELE PN2-VAK combines a self-resetting over/under voltage protector with a built-in kWh energy meter. A tri-color display shows voltage (red), current (green) and accumulated energy (blue) — ideal for rental-property sub-metering and tenant electricity billing while protecting the circuit from voltage and current faults.

Key Features

  • Voltage protection + built-in kWh energy meter
  • Tri-color display — voltage / current / kWh
  • Over-current setting 1–40A / 1–63A / 1–80A
  • Adjustable reset delay 0–999s (default 60s)
  • 35mm DIN-rail mounting

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.
