DIN or Rackmount

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.

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.

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.

Did not work after a few months.

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.

The product comes unassembled. You would think the product would come assembled for the price you pay. No instructions come with all the parts. The bar seems cheap and doesn't match the quality in the picture. The bar did fit in the rack mount, and all devices worked correctly when hooked up; even the PoE Access Points that require 30w power are working fine.

Beware Ham Radio Operators: Bought this for my Ham‘s PC Network to protect it from lightning or power surges finding their way to my Ethernet Switch. Since a ground wire was not included, I had to fabricate a special short wire to attach to the Ham station common ground (connects to the main house ground 8 feet away). Simple enough and installation was easy. Checked Internet speed with and without this device and saw no degradation 👍. When I got on the air, my digital mode transmissions went nuts. Somehow RF was finding its way into the item via the ground wire since disconnecting it solved the problem. So I wrapped three turns of the ground wire around a 1/2” ID ferrite clamp-on suppressor and reconnected the wire which solved the problem. Apparently this item has no internal RFI protection circuitry and is very susceptible to power in excess of 100 watts that is contained in coax and grounded equipment. This is a HUGE disappointment.

I think its worth the price. I have a handful of IP Cameras that run un-shielded over the property. Every year during storm season, I would loose cisco POE Switches, cable modems and once a server motherboard to lightning. After buying a few switches I installed this and have had ZERO issues with lightning dammage on network equipment.

Bonne mesure de protection. Merci

Il prodotto è valido, o perlomeno al momento non ho ancora avuto problemi, ma il prezzo mi sembra eccessivo. Ho acquistato in quanto la consegna era immediata, altrimenti esistono prodotti simili ad un terzo del costo di questo prodotto.
