STC-CCTV Coax Series

Tailored specifically to CCTV, data, audio and cable applications, these units are single Coax Surge Protection Devices implementing three-stage hybrid technology. They address overvoltage transients with a primary gas discharge tube (GDT), and secondary silicon avalanche diode (SAD) components. Overcurrent protection (e.g. sneak and fault currents) is mitigated with solid-state resetable fuses PTCs. The STC-CCTV units are designed in accordance with NFPA 780 (2004 edition) requirements, with up to 20kA of surge current capability. The STC-CCTV-75I model has an isolated ground and is recommended for use at the camera end.


  • Hybrid, three-stage technology using gas tubes, SADs and PTCs
  • Sneak/Fault Current Protection
  • Low Insertion Loss
  • Shielded Case
  • 5 Year Warranty
