The function of a power failure protector is that when the power is suddenly restored after an outage, it will not automatically reconnect the electrical appliances. The appliances can only be used again after manual reset. A power failure protector is a safe and energy-saving device installed in the main circuit of a single room. When a power outage occurs, if the power supply of the appliances that were originally in operation is not turned off, they will be immediately powered on when the power is suddenly restored. This not only wastes electricity but also may cause fires and personal safety accidents. Therefore, a power failure protector can prevent the automatic reconnection of electrical appliances when the power is suddenly restored after an outage. The appliances can only be used again after manual reset, thus achieving the purpose of safe and energy-saving electricity use.
