AC Surge Protectors

ETEK Solar AC Surge Protective Devices (AC SPD) provide primary and secondary surge suppression across single-phase and three-phase AC power distribution networks (TT, TN-S, TN-C-S systems). Available in Type 1 (Class I, 10/350µs) for main service entrances exposed to direct lightning currents, Type 2 (Class II, 8/20µs) for sub-distribution panels, and combined Type 1+2 models, our AC SPDs feature plug-in cartridge modules for fast, tool-free replacement without interrupting incoming power.
