Protection and safety
Telecom & computer line protection
OVR Cat-5 & Cat-6 Series

5
Combined Category D, C, B tested protector (to BS EN 61643) suitable to
protect twisted pair Ethernet networks, including Power over Ethernet (PoE),
with RJ45 connections. 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
• Suitable for systems signalling on up to eight wires of • Low capacitance circuitry prevents the start-up signal
either shielded or unshielded twisted pair cable • degradation associated with other types of network
• Very low let-through voltage (enhanced protection to protector
IEC/BS EN 62305) between all lines - Full Mode design • Low in-line resistance minimizes unnecessary reductions
capable of handling partial lightning currents as well as in signal strength to maximize signalling distance
allowing continual operation of protected equipment • Sturdy ABS housing with convenient holes for flat
• Repeated protection in lightning intense environments mounting, or vertically via TS35 ‘Top Hat’ DIN rail
• Unlike some competing devices, the ethernet SPDs • Substantial earth connection to enable effective earthing
provide effective protection without impairing the • Will protect all PoE powering modes A and B.

Installation
Connect in series with the network cable, either:
• Near to where it enters or leaves the building, or
• As it enters the network hub, or
• Close to the equipment being protected Accessories
