A shielded RJ-45 surge protector with eight lightning protection tubes installs between Ethernet and the device

  • Protects routers from lightning damage with eight protection tubes
  • Shields notebooks from surge strikes when installed near the device
  • Compact shielded aluminium alloy housing fits tight spaces measuring 43 by 13 by 15 mm
  • Simple inline RJ-45 installation between cable and equipment
  • Extends Ethernet connections while adding surge protection

Surge protection for RJ-45 Ethernet lines

This inline adapter shields network equipment from lightning-induced surges on copper Ethernet cables. It sits between the wall jack or PoE injector and the router, switch or laptop, diverting excess voltage through eight gas-discharge tubes. The shielded aluminium-alloy body measures 43 by 13 by 15 millimetres and installs without tools or external power.

Installers protecting wired LAN gear

Suits anyone who needs a passive, maintenance-free surge barrier for a single RJ-45 link running Cat5e, Cat6 or Cat6a cable. It does not supply power, so devices that rely on Power over Ethernet will continue to work, but the unit cannot protect fibre links, coaxial lines or equipment that requires a grounded multi-port panel.

Eight gas-discharge tubes per adapter

Each connector houses eight protection elements, one for every conductor in the RJ-45 interface, clamping transient voltages before they reach the attached device. The manufacturer advises placing the adapter within one metre of the equipment it guards for the lowest let-through voltage.

Questions about this item

How can I verify the RJ-45 lightning arrester is protecting my router after installation?

The adapter sits inline between the Ethernet cable and your router; if the link lights on both ports stay lit and the connection remains stable during storms, the eight protection tubes are doing their job.

What comes in the box and do I need any extra cables or tools?

The package contains one shielded aluminium-alloy RJ-45 coupler measuring 43 by 13 by 15 mm; you only supply the two Ethernet patch cords that plug into each side.

Which version of this surge protector should I choose for a standard Cat5e or Cat6 run?

Only one model is offered — a single RJ-45 female-to-female coupler with eight built-in protection tubes — so there are no capacity or version options to select.
