AMERICAN POWER CONVERSION CORP PTEL2 APC ProtectNet Analog/DSL Phone Line Surge Suppressor, Beige

Catastrophic Event Protection. SurgeArrest components such as MOVs and Thermal fuse ensure instantaneous reaction to lightning strikes and wiring faults. If the surge components are damaged due to power spike or over voltage, excess power cannot reach your equipment. Unlike the APC SurgeArrest products, most surge suppressors continue to let power through even after circuits have been damaged, leaving your equipment exposed to other damaging surges. Helps save energy - designed to limit the energy used by other products, potentially helping you reduce your carbon footprint and save money.
