Ten small silver boxes with RJ45 ports and grounding wires

BFKK

BFKK Ethernet Surge Protector 10 Pack RJ45 Gas Discharge Tube 1000 Mbps

SKU CH-ZY3J-AQ7J5

A pack of ten inline RJ45 surge protectors with gas discharge tubes for gigabit PoE+ networks

  • Pack of 10 protects multiple network runs
  • Gas discharge tubes shield all four wire pairs
  • Handles 5 kA 8/20 µs surge current
  • Ground wire and flanges enable secure mounting
  • Rated for 1000 Mbps PoE+ gigabit links

10-Pack Gigabit Surge Protectors

This ten-pack of inline RJ45 surge protectors guards Gigabit Ethernet and PoE+ links up to 1000 Mbps. Each unit uses gas discharge tubes on all four wire pairs to clamp transients from lightning strikes, voltage spikes or PoE overvoltages. The aluminium housing includes a 12 AWG ground wire and mounting flanges for wall, panel or rack installation.

Installers Protecting PoE Gear

Suited for technicians securing routers, switches, cameras, modems or repeaters on exposed CAT5, CAT5e or CAT6 runs. The 60 V, 720 mA HPoE rating covers standard PoE+ deployments, while bidirectional clamping handles line-to-line and line-to-ground surges. Buyers needing fibre isolation, 10 Gbps throughput or outdoor-rated enclosures should consider other solutions.

Inline Protection for Rack Builds

The protector sits between the incoming cable and the network device, requiring only a ground connection and optional screw mounting. Its compact flange design frees rack space compared with bulkier DIN-rail units, and the ten-unit pack lets one installer secure multiple ports in a single visit. No external power supply or configuration is required.

Questions about this item

What type of Ethernet cable and PoE standard must my network already use for these protectors to work?

They support CAT5, CAT5e and CAT6 cables running at 10/100/1000 Mbps and handle PoE+ (HPoE) up to 60 V and 720 mA on all four pairs.

Will the gas discharge tubes on all eight wires still protect my older 100 Mbps cameras and switches?

Yes, the GDTs cover every wire pair and the bidirectional clamping works at any speed up to 1000 Mbps, so legacy 10/100 devices remain protected.

How can I verify each unit is clamping surges correctly after I mount the ten protectors?

With the 12 AWG ground wire secured and the mounting flanges screwed to a grounded rack or panel, the line-line and line-ground paths are complete; a qualified installer can then test clamping voltage with a surge generator.
