Surge Protection Device (SPD) is designed to protect electrical installations and connected equipment from lightning strikes, transient overvoltages, and power surges. It safely diverts excess surge energy to ground, helping prevent damage to sensitive electrical and electronic equipment. The surge is commonly installed in main distribution boards, control panels, industrial facilities, commercial buildings, and residential power systems.
