Self-resetting over-voltage and under-voltage protector is the basic component of electrical system. It has the characteristics of compact structure, long service life, safety and reliability, beautiful appearance and convenient installation. It is suitable for protection in household and shopping mall power distribution systems.

If there is an overvoltage in the power supply line, the undervoltage will cause damage to the electrical equipment on the line and affect the normal operation of the electrical system. Therefore, a protective electrical switch is needed to protect the electrical equipment on the line from damage to the electrical equipment. The self-resetting over-voltage and under-voltage protector can effectively solve the problem of over-voltage and under-voltage caused by the neutral line fault of the electrical system, and ensure the safety of single-phase electrical equipment.

Once the power supply line has a fault condition such as overvoltage or undervoltage, the self-resetting overvoltage and undervoltage protector will automatically disconnect according to the fault condition, cut off the power supply line, and protect the electrical equipment on the line from overvoltage and undervoltage. When the fault in the line is removed and the voltage in the line returns to normal, the self-resetting over-voltage and under-voltage protector automatically detects the change of the voltage value, automatically turns on the circuit to ensure that the terminal electrical equipment operates normally under unattended conditions, improving The stability of the power supply line.

It can be seen that the role of the self-resetting over-voltage protector in the electrical system is very important, especially for the distribution line of single-phase electrical equipment, which is a key factor for the safe operation of single-phase electrical equipment.
