Surge Suppressors protect connected equipment by stopping damaging surges and filtering disruptive line noise. When a surge enters the surge suppressor (through the power, modem, network and/or coax lines) internal components (such as Metal Oxide Varistors) automatically absorb some of the excess voltage and safely channel the remaining voltage through the ground wire and away from the facility. The surge suppressor passes on clean power to connected devices, free of damaging surge voltage. If an incoming surge is significantly intense (to the point of overheating internal components), safe thermal fusing will automatically shut off power, sacrificing the surge suppressor in order to save connected equipment. When line noise enters the surge suppressor (through the power, modem, network and/or coax lines) internal components (such as capacitors) filter the interference. The surge suppressor passes on clean power to connected devices, free of disruptive line noise.
