Network surge protector for RJ45 lines

The Tripp Lite DNET1 is a compact suppressor that installs inline on an Ethernet or serial link to shield connected workstations, printers and hubs from transient voltages. It accepts both 120V and 230V environments and uses RJ45 input and output jacks for straightforward deployment.

Clamping at 7.5 V RMS with 750 A capacity

The device limits let-through voltage to 7.5 V RMS and can divert surge currents up to 750 amps, which defines the practical protection ceiling for the supported line types. It covers 10/100Base-T, token ring, AS400/Sys3x and RS422 wiring across all eight conductors, so faster Ethernet standards or non-RJ45 interfaces fall outside its scope.

Replaces unprotected patch cables

Adding the DNET1 upgrades a plain data path by inserting coordinated clamping on every wire pair, a step up from relying on mains surge strips alone. The jump is worth it when lightning, electrostatic discharge or ground loops threaten network hardware and the installation uses one of the listed RJ45-based protocols.

Questions about this item

Which network standard should I pick for the RJ45 surge protector?

The unit handles 10/100Base-T, token ring, AS400/Sys3x and RS422 lines on all eight wires, so choose the one matching your existing cabling.

What does the 7.5 V clamping voltage mean for my equipment?

It limits transient spikes to 7.5 V RMS on the data lines, keeping network cards, hubs and terminals below their damage threshold.

What interface does the DNET1 use and what throughput does it cap at?

It uses RJ45 connectors wired for 10/100Base-T, token ring, AS400/Sys3x and RS422, passing signals up to 100 Mbps on all eight conductors.
