CCTV, Data, Audio and Cable Protection.
Built specifically for CCTV, data, audio and cable applications, the STC-CCTV Series provide three-stage hybrid surge protection for data transmitted over coaxial cable. A primary gas tube and secondary silicon avalanche diode components protect equipment from overvoltage transients, while sneak and fault currents are mitigated with solid-state resettable fuses (PTCs). These units are designed in accordance with NFPA 780 (2004 edition) requirements, offering up to 20 kA of surge current capability. The STC-CCTV-75I model has an isolated ground and is recommended for use at the camera end.
