Combined Category D, C, B tested protector (to BS EN 61643) suitable for
coaxial CCTV cables with BNC connectors (ESP CCTV/B) or twisted pair CCTV
lines (ESP CCTV/T) on systems with either an earthed or an isolated screen.
Not suitable for use on broadcast, satellite or cable TV systems. For use at
boundaries up to LPZ
0
to protect against flashover (typically the service
entrance location) through to LPZ 3 to protect sensitive electronic equipment.
Specific systems protection
ESP CCTV Series
Installation
Connect in series with the CCTV cable in a convenient place
close to the equipment being protected. For outdoor CCTV
cameras, protectors should be mounted in the junction box, or
in a separate enclosure, close to the camera. Protect central
control and monitoring equipment inside the building by
installing protectors on all incoming or outgoing lines, either:
a) near where they enter or leave the building, or
b) close to the equipment being protected (or actually within
its control panel).
Accessories
When CCTV protectors are installed in groups, or alongside
protectors for signal and mains power lines, these can be
mounted and earthed simultaneously on a CME kit. A CME
4 will accommodate the video, telemetry and power
protectors to a camera. If protectors cannot be incorporated
within an existing panel or enclosure, WBX enclosures are
available for up to 4, 8, 16 or 32 protectors and their
associated CME kit. The WBX 4/GS is a secure IP66
enclosure suitable for a CME 4 and associated protectors.

Features & benefits
–– Very low let-through voltage (enhanced protection to
IEC/BS EN 62305) between all lines - Full Mode protection
–– Full Mode design capable of handling partial lightning
currents as well as allowing continual operation of
protected equipment
–– Repeated protection in lightning intense environments
–– 100 MHz bandwidth prevents the degradation of high
frequency signals
–– Low in-line resistance to minimize unnecessary reductions
in signal strength and maximizes signalling distance
–– Very low reflection coefficient/VSWR ensure that the
protector doesn’t disrupt system operations
–– Suitable for either earthed or isolated screen systems
–– Sturdy, conductive ABS housing for 2 way shielding -
preventing emissions & providing signals with immunity
from external interference
–– Convenient holes for flat mounting on base or side
–– Built-in DIN rail foot for easy installation on a top hat DIN rail
–– ESP CCTV/T has colour coded terminals for a quick and
easy installation check - grey for the dirty (line) end and
green for the clean end
–– Substantial earth stud to enable effective earthing
–– Integral earthing plate for enhanced connection to earth
via CME kit
–– ESP CCTV/B has Network Rail Approval PA05/02510.
NRS PADS reference 086/023410
Application
Use these protectors on the video cable to outdoor CCTV
cameras and central control and monitoring equipment.
NOTE:
Camera telemetry or control lines should be protected with a suitable Lightning Barrier from the ESP D or E Series. Protectors for the power supply to
individual cameras (e.g. ESP 240-16A) and the mains supply to the control room (e.g. ESP 240 D1) are available. For coaxial RF (ESP RF Series) cable protectors
and CATV systems (ESP CATV/F) are also available.
