The self-resetting over-voltage protector is a commonly used protective device that uses a plastic insulator as the device housing to effectively isolate the conductors to ensure safety during daily operation. The utility model has the advantages of simple structure, safety and reliability, long service life, convenient installation and beautiful appearance, and is the preferred protective electrical product for large, small and large enterprises in China.

The self-resetting over-voltage and under-voltage protector is implanted in the line. Once the over-voltage and under-voltage of the power supply line exceed the specified value, the self-resetting over-voltage and under-voltage protector will act quickly, automatically disconnect, cut off the line, and ensure the equipment on the line. Security. It also has a detection function to automatically detect the voltage on the line. When the voltage on the line returns to the normal value, the self-resetting over-voltage and under-voltage protector will automatically close and restore the normal power supply.

The self-resetting over-voltage protector has a relatively compact structure, and all the components are sealed in the plastic casing to prevent corrosion of the components and effectively improve the reliability of the components. In addition to the protection function of over-voltage and under-voltage, the self-resetting over-voltage and under-voltage protector also has functions such as phase failure protection and broken line protection. Many practical functions can effectively solve the problem when the line is faulty. The safety of equipment and power lines plays an important role.

The installation and use of the self-resetting over-voltage protector greatly improves the reliability of the electrical system, automatically disconnects when the fault occurs, and automatically closes after the fault is eliminated, which can reduce the strength of the staff to a certain extent, save human resources and time for the user. Provide a high-quality distribution network.
