Data & signal protection
OVR E Series
5
Combined Category D, C, B tested protector (to BS EN 61643) suitable for
twisted pair signalling applications which require either a lower in-line
resistance, an increased current or a higher bandwidth than the OVR D Series.
Also suitable for DC power applications less than 1.25 Amps. Available for
working voltages of up to 6, 15, 30, 50 and 110 Volts. 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.
Features & benefits
• Very low let-through voltage (enhanced protection to • Screen terminal enables easy connection of cable screen
IEC/BS EN 62305) between all lines - Full Mode protection to earth
• Full Mode design capable of handling partial lightning • Strong, flame retardant, ABS housing
currents as well as allowing continual operation of • Built-in DIN rail foot for simple clip-on mounting to top hat
protected equipment DIN rails
• Repeated protection in lightning intense environments • Colour coded terminals give a quick and easy installation
• Very low (1 Ω) in-line resistance allows resistance critical check - grey for the dirty (line) end and green for clean
applications (e.g. alarm loops) to be protected • Substantial earth stud to enable effective earthing
• High (1.25 A) maximum running current • Supplied ready for flat mounting on base or side
• High bandwidth enables higher frequency (high traffic or • Integral earthing plate for enhanced connection to earth

Application Installation
Use these units to protect resistance sensitive, higher Connect in series with the data communication or signal line
frequency or running current systems, e.g. high speed either near where it enters or leaves the building or close to
digital communications equipment or systems with long the equipment being protected (e.g. within its control
signal lines. panel). Either way, it must be very close to the system’s
earth star point. Install protectors either within an existing
cabinet/cubicle or in a separate enclosure.

NOTE: Slim Line (OVR SL) and ATEX (OVR SLX) are available. For many twisted pair data and signal applications, the lower cost OVR D Series may be suitable.
For applications requiring higher current (1.25 A to 4 A) or ultra-low in-line resistance, the OVR H Series protectors may be more suitable.
