Power supply lightning protection socket for household use
This series of product is applicable to the fine protection of single phase power supply circuit against lightning and electric surge. With national standard universal socket design and multi-shape power supply socket, it's specially applicable to the lightning protection for household use. It has built-in automatic safety device, which can break automatically due to superheat or breakdown by lightning stroke to protect the normal operation of electronic equipment. Besides, it also has deterioration indication light and double earth terminal, and can ground through the earth lead in the lightning protection socket. When it's not well grounded, it can ground through the special outside earth terminal.
