Features: 1. The protector includes overvoltage protection, undervoltage protection, and other protective functions. 2. The main feature is that when the line experiences overvoltage, undervoltage, or overcurrent conditions, the product can instantly cut off the power supply to protect electrical equipment from damage. When the line voltage returns to normal, the protector automatically restores power. 3. It is primarily used for overvoltage, undervoltage, or overcurrent protection in residential electrical distribution panels or for single-phase power equipment. 4. Suitable for single-phase AC voltage 230V, 50/60Hz, with a rated working current of 63A or below. 5. Low power consumption and long mechanical life.
