Overvoltage and undervoltage protection relay, DIN rail 63A to 220V, with dual display for domestic use.

Adjustable voltage current protector with dual display D, suitable for single-phase AC 220V, 50/60Hz, rated working current 63A. It is primarily used for residential domestic junction box entry or for overvoltage, undervoltage, or overcurrent protection of distribution lines for single-phase electrical equipment. Its main feature is that when a circuit experiences overvoltage, undervoltage, or overcurrent problems, the product can instantly cut off the power to protect the electrical equipment from damage. Furthermore, the protector can automatically restore power when the circuit voltage returns to normal. The overvoltage, undervoltage, and overcurrent values of this product can all be configured by the user and adjusted based on local practical conditions.
