Surge Protective Device WU5-T2-40

AC SPD (AC Surge Protective Device) refers to a surge protector used in AC power supply systems. It is mainly used to suppress transient overvoltages caused by lightning strikes, switching operations, electrostatic discharge, etc., and to safely discharge surge current, thereby protecting the power distribution equipment, control devices, and terminal loads (such as PLCs, frequency converters, instruments, lighting systems, etc.) in the AC circuit.
