APC PNET1GB Standalone Surge Protector for 10/100/1000 Ethernet Network

The PNET1GB Surge Protector, part of APC's ProtectNet series, offers complete protection to your 10/100/1000 Base-T networks and Power over Ethernet (PoE) systems in the event of unexpected surges in voltage from lightning, wiring faults, or utility problems.

Boasting an IEEE let-through rating of 60 volts, the PNET1GB is designed to prevent more than 60 volts of electricity from reaching your equipment. Since higher let-through rates can increase the risk of damage to your electronics, the 60-volt rating of the PNET1GB indicates that less voltage may strain and hinder the performance of your system.

The PNET1GB is built around a metal oxide varistor (MOV), which instantaneously diverts excess surge voltage to the ground. Because it responds in under a nanosecond, the MOV can keep your equipment running while providing complete surge protection.

A thermal fuse works in conjunction with the MOV to cut the unit's connection to electrical current if it reaches a certain temperature. This means that even if the MOV is damaged by an overwhelming surge, the thermal fuse acts as a fail-safe feature, disconnecting your equipment from the power source so that excess voltage is unable to reach your network.
