Furse ESP Cat-5 & Cat-6 Series

Combined Category D, C, 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 0B to protect against flashover (typically the service entrance location) through to LPZ 3 to protect sensitive electronic equipment.

Features and 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 BS EN 62305) between all lines - Full Mode protection
  Full mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment
  Repeated protection in lightning intense environments
  Unlike some competing devices, the 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 minimises unnecessary reductions in signal strength to maximise 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
  Supplied with short (50 cm) Cat-5e UTP or Cat-6 STP cable to enable neat installation

Data Sheet


Connect in series with the network cable, either:

a) near to where it enters or leaves the building, or

b) as it enters the network hub, or

c) close to the equipment being protected

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