APC Surge Protection Module For Rs232 Replaceable 1u F/ Prm4/prm24 Rackmount Chassis

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 Rack-mount ProtectNet family offers a modular approach to protecting a variety of data lines, including telephone lines, network lines, coax cables and more. Installing any combination of individual surge protection modules into either the four- or 24-position chassis and connecting them to earth ground will prevent back-door surges from ruining your productivity and costing you money.
