Three-Phase SPDs

Three-phase surge protective devices (SPDs) provide NEC-required protection against transient voltage surges from lightning strikes, current switching, start up, shut down, and power surges. Littelfuse makes three models of Type 1 and Type 2 single-phase SPDs that, respectively, use metal oxide varistors (MOVs), gas discharge tubes (GDTs), or MOVs, TVS diodes, and fuses to handle excess voltage.
