Review on 🌩️ Tupavco TP303 Ethernet Surge Protector Outdoor - Gigabit 1000Mbs LAN Network Thunder Lightning Surge Protection Suppressor/Arrester for PoE+ by Oliver Phelps

I use them often. They are inexpensive and meet the requirements. Plug & Play saves time by not stripping cables or punching wires. Simply connect each RJ45, attach a ground wire and install. The only problem is that each cable should have 2; one at the entrance of the building and one at the equipment. They are not suitable for outdoor use in places with high humidity, especially near the sea. Otherwise they work in this price range. Update: suck rubber seals. They do not seal cable entries. In rooms with high humidity, the electronics are exposed to moisture or splashing water. That means I have to take an extra step to seal the blocks with silicone and that's a problem when the cable needs to be unplugged.
