TAA Compliant

The ComNet CopperLine® CLESP provides highly effective voltage surge and transient protection for Ethernet-compatible equipment, including Ethernet switches, media converters, EoVDSL modems, ComNet CopperLine Ethernet over UTP transmission extenders, etc. The mating RJ-45 connector on the CLESP plugs directly into any 10/100/1000Base-T Ethernet port, making the installation simple and quick. Protection is provided to IEC specification EN55024; Immunity Characteristics for Continuous and Transient, Conducted and Radiated Disturbances. Electrostatic discharge (ESD) protection is also provided. For maximum effectiveness, the grounding tab of the CLESP must be securely connected to the frame ground of the installation.

Features for CLESP

  • Highly effective voltage surge and transient protection for Ethernet-compatible equipment
  • Simple and quick installation
  • Economical: Install on those selected Ethernet ports requiring surge and transient protection
  • Provides additional Ethernet port protection for IP cameras, DVRs and NVRs
  • Fully Compatible with any 10/100/1000 BaseT Ethernet port
  • PoE Compatible: IEEE 802.3af and 802.3at compliant for PoE and PoE Plus
  • No additional ground cable required; Grounding tab is integral to the protector
  • Tested and certified to EN61000-4-5 and EN55024 surge standards
  • Compact form-factor saves space in those installations where space may be at a premium.


  • Protection of Ethernet transmission equipment subjected to environments where potentially damaging voltage transients or high levels of electrical noise may be present
  • Long distance UTP cable runs
  • Ethernet Networks in electrically-noisy industrial environments
  • IP cameras and other network equipment operating in environments such as parking lots, warehouses, and perimeter surveillance applications where lightning or other damaging electrical disturbances may exist
