Voltage Protector
PN2-VA2 Voltage Protector
TPKELE PN2-VA2 is a self-resetting over/under voltage protector with a dual digital display showing voltage (red) and current (green). It disconnects the load on over-voltage, under-voltage and over-current, then reconnects automatically after an adjustable delay — ideal for residential distribution boards and home appliance protection in unstable grid areas.
Key Features
- Self-resetting over / under voltage protection
- Dual display — voltage (red) + current (green)
- Max working current 40A / 63A / 80A optional
- 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.
