The RJ45-S is designed to protect devices connected through network cabling on a Direct Current (DC) supply. The device does not filter. It offers spike and surge protection to ensure data transfer speed is maintained. The product is relying on a solid earth connection to maximise the efficiency of the protection circuit capability. The earth connection is critical to ensure that when a dangerous high voltage spike or surge is detected the RJ45-S is able to divert this threatening voltage down to earth in the first instance.

If the surge is too great to divert all the excess energy back to earth then the RJ45-S protection circuit will absorb the residual surge. The RJ45-S is designed to sacrifice itself if it is unable to absorb the surge and in doing so protect the connected equipment. By sacrificing itself it can prevent the connected equipment from damage and save on downtime associated costs. Replacement of the RJ45 protection module is simple and very quick.


Introducing the Smart Series RJ45-S single, in-line high speed network protection. Line induced spikes and voltage surges that could damage the Network Connected Devices are easily suppressed by the RJ45-S. This unit is DIN rail mountable and fits in-line between the Source Device and the connected unit (ie Network Camera and NVR, PC and Network Switch). The unit uses two standard RJ Connectors for easy connecting and disconnecting. Damaging energy is diverted to system earth by means of fast acting components, the earth connection is connected via a plug allowing for quick removal or replacement of the device.

What causes spikes and surges in network cabling?

  • Power cables crossing network cables.
  • Equipment induced transients
    and surges.
  • Earth Potential Rise – this is where lightning strikes nearby and energises the surrounding earth. This energised area can cause surges to travel through, up, into and around walls and frames
    of structures. Network cabling is often housed in wall cavities and this surge then injects itself into the network cabling travelling through the cable and damaging connected equipment.
