The function of the power failure protector is that when a sudden call comes after the power failure, it will not automatically connect to the general electrical appliance, and it must be manually reset to use the electrical appliance to work again.
The power failure protector is a safe, energy-saving device that is installed in the total circuit of a single room. When there is a power failure, if the electrical appliance originally in the working state forgets to disconnect the power supply, when the sudden call, the electrical appliance will be immediately powered on, which will not only waste electrical energy, but also may lead to the occurrence of fire and personal safety accidents. Therefore, the power failure protector can be suddenly called after the power failure, not automatically connected to the general electrical appliances, must be manually reset to use the electrical appliances to work again, so as to achieve the purpose of safety and energy saving electricity.
