Surge Protection Device

Surge Protection Devices (SPDs)

Surge protection devices divert lightning-induced and switching transients to earth before they reach sensitive equipment. This range stocks Mersen Type 1, Type 2 and Type 1+2 SPDs and Modulostar fuse gear, Lovato Electric SG pluggable SPDs and replacement modules, and Finder and ABB surge arresters, for single- and three-phase systems.

Filter by SPD type, nominal voltage and discharge current. DC-side protection for solar systems is under PV Surge Protection.
