Surge Protective Device

The surge protective device, also known as surge protector or lightning arrester, is a protection device used in electrical and electronic systems to safeguard equipment against instantaneous overvoltage and surge impacts caused by lightning strikes, power grid fluctuations and other factors.It conducts and discharges surge current in an extremely short time, clamps the abnormal high voltage on the line to a safe range, prevents equipment damage due to overvoltage, and ensures the stable operation of power supply and control systems.It is widely used in power distribution cabinets, PLC systems, instruments, communication equipment, household appliances and various industrial automation scenarios.
