Features: _x000D_1. The protector has over voltage protection, under voltage protection and other functions _x000D_2. The main feature is that the line has overvoltage or undervoltage, overcurrent condition, the product can cut off the power supply instantaneously, protect the electrical equipment from damage; when the line voltage returns to normal, the protector can automatically and normally _x000D_3. It is mainly used for the protection of over-voltage, under-voltage or over-current in the distribution line of residential household box or the protection of single-phase power equipment. _x000D_4.
