Project Description



Surge arrester with BNC for protecting Closed Circuit Television (CCTV), video, camera, and surveillance systems to avoid being influenced by leakage pickups.

  • Easily adaptable due to BNC sockets
  • For installation in conformity with the lightning protection zone concept at the boundaries from 0B – 2 and higher
  • Application: CCTV, video, camera and surveillance systems
