AC Surge Protection Device

AC Surge Protective Device

AC surge protection devices (SPDs) are specifically designed for low-voltage power distribution systems. They include Type 1, Type 2, and Type 1+2 full-mode AC SPDs, single-phase/three-phase surge protectors, and N-PE modules. These devices meet IEC/UL 1449 standards and provide transient overvoltage protection for buildings, factories, and charging stations.
