SP-POE-24 is a 24 port in-line RJ45 Ethernet Cat6 cable surge protector. It installs simply on a Cat5, Cat 5e or Cat6 4 twisted pair cable. Device is using special diodes and gas discharge modules for effective lightning protection. It protects any RJ45 Ethernet based device like switches, DSL modems, routers, computers, etc. The Ethernet surge protector is a 19" wide and 1U height rack mountable device with special grounding wire.
Note: This special surge protector version does SUPPORT the IEEE 802.3af PoE standard (Power over Ethernet). You can use such protector on PoE active cabling. The compatibility is assured with the IEEE 802.3af standard by supporting a much higher clamping voltage of 53V.

Features of SP-POE-24 RJ45 Ethernet surge protector
Fast energy absorption on over-voltage
