      FAQ

      1. What appliances can this protector safeguard?
      It protects refrigerators, air conditioners, washing machines, and other voltage-sensitive appliances.

      2. Why is voltage protection critical for appliances?
      Long-term under-voltage or over-voltage can significantly shorten appliance lifespan.

      3. Does it reconnect automatically?
      Yes. Power is restored automatically once voltage stabilizes.

      4. Is installation complicated?
      No. DIN-rail installation makes setup quick and simple.

      5. Can it be supplied in bulk?
      Yes. We provide wholesale supply and OEM services as a factory manufacturer.
