DIN-Rail mount BNC connector data signal surge protective
devices for coaxial cable systems
Common applications include protecting outdoor
video surveillance systems or video control
centers or coaxial data lines. For BSPD5BNCDI,
the cable shield is indirectly grounded via a gas
discharge tube to avoid being influenced by
leakage pickups.

BSPD5BNCDD
BSPD5BNCDI
Description:
The Bussmann™ series BSPD5BNCDD and
BSPD5BNCDI two-stage DIN-Rail mounted
surge arresters are for protecting coaxial cable-
connected systems (such as video and camera
systems) from potential damage.
The BSPD5BNCDD features direct (VCD) shield
connection while the BSPD5BNCDI features
indirect shield connection (VCID) to prevent
leakage pickups.
The BSPD5BNCDD and BSPD5BNCDI shielded
surge arresters are mounted on the supplied
bracket with cable lug or mounted on a rack-
mounted DIN-Rail with suitable grounding.
BNC connector terminated data or video signal
cables are plugged into surge arrester with the
equipment plugged into the protected side.

Direct vs. indirect shielding - example
Apply the BSPD5BNCDD (direct shield) at the equipment location
and apply the BSPD5BNCDI (indirect shield) near exterior protected
equipment. The indirect shield grounding at the exterior device
will help avoid picking up leakage currents that can degrade
signal quality while providing surge protection when needed. See
illustration below for installation locations.
