The ESP Cat-6/POE is for telecom and computer line protection. A combined Category D, C, and B tested protector (to BS EN 61643) suitable to protect twisted pair Ethernet networks, including Power over Ethernet (PoE++), with RJ45 connections.

For use at boundaries up to LPZ 0 to protect against flashover (typically the service entrance location) through to LPZ 3.

Features & Benefits

  • Suitable for systems signalling on up to eight wires of either shielded or unshielded twisted pair cable.
  • Very low let-through voltage (enhanced protection to IEC/BS EN 62305) between all lines – Full Mode design capable of directing partial lightning current to Earth, as well as allowing continual operation of protected equipment.
  • Unlike some competing devices, ethernet SPDs provide effective protection without impairing the system’s normal operation.
  • Low capacitance circuitry prevents the start-up signal degradation associated with other types of network protector.
  • Low in-line resistance minimizes unnecessary reductions in signal strength to maximize signalling distance.
  • Sturdy ABS housing with convenient holes for flat mounting or vertically via TS35 ‘Top Hat’ DIN rail.
  • Substantial earth connection to enable effective earthing.
  • ESP Cat-6/PoE has additional components fitted to protect PoE power sourcing equipment (PSE) and powered devices (PD).


Use these protectors on network cables that travel between buildings to prevent damage to equipment, such as computers, servers, IP camera systems, repeaters, and hubs. Suitable for computer networks up to Cat-6A cabling.

  • To protect up to 1000baseT/ 10GbaseT networks with Cat-6/Cat-6A cabling use ESP Cat-6
  • To protect up to 1000baseT/ 10GbaseT Power over Ethernet (PoE) networks with Cat-6/Cat-6A cabling use ESP Cat-6/PoE


Connect in series with the network cable, either:

Near to where it enters or leaves the building, or as it enters the network hub, or close to the equipment being protected.

This should be close to the system’s Earth star point (to enable a good connection to Earth).
