UL Listed 497B In-line Surge Protective Device for BNC Connector Cable Systems
Description
The Cooper Bussmann BSPD5BNCSI two-stage in-line surge arrester is for protecting coaxial cable-connected systems (such as video and camera systems) from potential damage.
The BSPD5BNCSI shielded surge arrester is plugged into coaxial terminal equipment or connections. Common applications include protecting outdoor video surveillance systems or video control centers. The cable shield is indirectly grounded via a gas discharge tube to avoid being influenced by leakage pickups. The arrester input is used as a socket and the protected output as a plug.
• UL 497B Listed
• Plug-in surge protective device for easy retrofitting
• Directly plugs into terminal equipment with BNC coaxial connections
• Integrated indirect shield grounding avoids leakage pickups
