Combined Type 2 and 3 tested protector (to BS EN 61643) for use on low
current (up to 16 A) single phase systems to protect connected electronic
equipment from transient overvoltages on the mains supply, e.g. CCTV systems,
fire/intruder alarm panels.

Application Installation
Use these protectors on low current mains power supplies, Connect in-line with the power supply usually either within
e.g. CCTV cameras, alarm panels and telemetry equipment. the equipment panel (or for CCTV cameras, in an enclosure
close by), or on the fused connection that supplies
equipment. To protect equipment inside a building from
transients entering on an outgoing feed (e.g. to CCTV
cameras or to site lighting) the protector should be installed
as close to where the cable leaves the building as possible.
Protectors should be installed either within an existing
cabinet/cubicle or in a separate enclosure.

Accessories Connect in-line on supplies fused up to 16 A.
If several OVR 240-16A protectors are to be installed together, or if one is in use Note how the protector can also be
alongside OVR SPDs for video or signal lines, these can be simultaneously mounted earthed from its earth stud.
and earthed on a OVR CME kit and housed in a suitable OVR WBX enclosure.
