Data/signal line surge protection
e STC-CCTV Series is tailored specically to CCTV,
data, audio and cable applications. ese units are
single Coax Surge Protective Devices implementing
three-stage hybrid technology. ey address overvoltage
transients with a primary gas tube, and secondary
silicon avalanche components. Over-currents (e.g.
sneak and fault currents) are mitigated with solid-state
resetable fuses (PTCs). e STC-CCTV units are
designed in accordance with NFPA 780 (2004 Edition)
requirements, with up to 20kA of surge current
capability. e STC-CCTV-75I model has an isolated
ground and is recommended for use at the camera end.
