What Is Low And High Voltage Protectors ?

The low and high voltage protector is a device used to safeguard electrical equipment. It can promptly cut off the circuit when the voltage is higher or lower than the preset value, preventing damage to the electrical equipment. Its working principle is based on the attraction and disconnection of an electromagnet. When the voltage in the electrical system is higher or lower than the set value, the internal circuit of the protector processes the signal and controls the state of the electromagnet
