CZVA1 Digital Voltage Protector Socket
TPKELE CZVA1 is a plug-and-play adjustable digital voltage protector socket for EU (Schuko), UK and South Africa plug standards. It cuts power on over-voltage or under-voltage and automatically restores after a set delay, with a digital LED display and Power / SET / Up / Down buttons — protecting refrigerators, air conditioners, TVs and washing machines from unstable mains.

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.
