APC by Schneider Electric ProtectNet PRM4 Surge Suppressor
The majority of all surge-induced damage is caused by surges and spikes traveling along unprotected data lines. These surges originate from a wide variety of sources, including static charge buildup and lightning strikes. Left unprotected, your data lines expose network cards, A/V components, modems and other network equipment to damaging electrical transients. The ProtectNet family of stand-alone surge suppressors protects individual data lines, including telephone and network lines, coax cables, and more. Inserting a ProtectNet in your data line and connecting it to earth ground prevents back-door surges from ruining your productivity and costing you money.
