Gigabit Ethernet Surge Protectors with PoE Protection




Surge protection for critical data networks.  Suitable for use with Gigabit Ethernet.

  • Available as either a single port unit or a 24 port patch panel
  • Compatible with 10/100/1000BaseT networks and Power-over-Ethernet systems
  • Up to 1000Mbps data rate
  • Compatible with 48V power over Ethernet systems
  • 63V PoE clamping voltage
  • 1.5KA surge discharge current
  • All 8 pins protected
  • Shielded RJ45 jacks and metal enclosure for EMI noise suppression


The SP-GPOE-24 is a 24-port Gigabit Ethernet PoE surge protector rack designed to protect all 8 lines used in standard CAT5e cable. This product is compatible with 100/1000Base-T networks and 48V Power Over Ethernet system. The Standard 802.11af allows the methods of implementing POE. The SP-GPOE-24 applies protection to the data pairs (pins 1/2 and pins 3/6) and power over the unused pairs (pins 4/5 and pins 7/8). The SP-GPOE-24 protection is provided on all 8 Ethernet pins (6.8V clamping on Data pins 1, 2, 3, 6 and 53V clamping on POE pins 4, 5, 7, 8). Network connections are made via standard female RJ- 45 connectors. Grounding is accomplished via a ground wire.

A surge protector is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold. The SP-ETH-01 will ensure the reliable operation of RJ-45 twisted pair based networking equipment running Ethernet. Single unit and rack mountable surge protectors are both available.
