DIN or Rack Mount

I installed this surge protector between my cable modem and my router today. Easy peasy. Plug the Ethernet cables into each end (marked "Line" and "Equip") and attach the ground terminal to something grounded. (I used a 12AWG solid wire and a ground screw on my uninterruptible power supply.) Running Ookla Speedtest verified no degradation of signal. Hopefully, I'll never find out if it works.

This surge protector is clearly well-made (and others have mentioned that it saved their equipment). The metal RJ45 jack frames are connected to each other and to the ground connection, so it is compatible with shielded cable in the sense that it will conduct the shield connection. However, the device itself is not shielded (I took it apart to inspect how it was constructed). The case is plastic, so the device is a potential source of EMI entry. If you're looking for a shielded version that is completely encased in metal connected to ground, see Tupavco's TP302 (https://amzn.to/3IRJsaq) and my review about it.

Quick install, just using it with double stick tape to my switch, protecting an exterior Ubiquity PoE camera.

Through my career in instrumentation I have seen that copper wires run between buildings are vulnerable to lightning. Only gas tubes are truly effective for this and do not load the signal much. If you, like me, wonder if these will work OK, here is my setup, which works fine at 100Mb: About 75 feet of direct burial cat 5e to an outbuilding. The cable has been in the ground for about 7 years but not previously used for Ethernet. There is a 66 block at each end. I tried unsuccessfully to put RJ45’s on the underground cable, but it was impossible, the wire is too large. I know 66 blocks are not supposed to be used for 100Mb but it works fine. A short cat5e cable runs to the arrestor. Be sure the DIN rail is well grounded.

Did not work after a few months.

I was blowing one port on my router nearly every electrical storm. Frontier i think was getting tired of replacing them as i lost four routers in five months. I live on the highest natural point in central florida which is reported to have more lighting strikes than any place in the USA. Since i installed this i haven't lost a Ethernet port and have gone through one hurricane and seventeen major electrical storms. When I installed it i used one of the ideas of another reviewer thank you by the way. I did not use the ground wire supplied by the vendor but ran a 12 AWG multi strand wire from the unit to a three prong 15 amp replacement; plug's grounding pin. All other pins or spades on the plug remained empty and covered internally with heat shrink. Plugged into a outlet within three feet of the surge protector. Fantastic solution will now add these to all my ports entering the router and at my ORBI Wifi units.

Whether it performs as it should I don't know yet, However my complaint is that it shows a ground wire option but they don't send you the wire. Update: The description doesn't explicitly say that the wire was included so my fault for assuming that it was.

Easy to install, I hope I NEVER find out they do not work!

Bonne mesure de protection. Merci
