      FAQ

      1. What is the purpose of the time delay function?
      The delay prevents unnecessary tripping caused by short-term voltage fluctuations, improving system stability.

      2. When does the delay activate?
      The delay applies mainly during power restoration, allowing voltage to stabilize before reconnection.

      3. Is this suitable for motor loads?
      Yes. Motors benefit greatly from delayed reconnection, reducing mechanical and electrical stress.

      4. How is this device installed?
      It is mounted on a standard DIN rail inside distribution or control panels.

      5. Is bulk purchasing available?
      Yes. As a factory-direct supplier, we support wholesale and large-volume orders.
