Mains power protection
ESP 5A/BX & 16A/BX Series
Combined Type 2 and 3 tested protector (to BS EN 61643) for use on low
current (up to 5 or 16 A) single phase systems to protect connected electronic
equipment from transient overvoltages on the mains supply, e.g. fire/intruder
alarm panels. Protectors with /BX suffix come ready-boxed, to IP66, for use in
dirty or damp environments. Available for 90-150 Volts, 200-280 Volts and
232-350 Volts supplies. For use at boundaries LPZ 1 through to LPZ 3 to protect
sensitive electronic equipment.

Installation
Connect in-line with the power supply usually either within 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.
Unless ready boxed, protectors should be installed either
within an existing cabinet/cubicle or in a separate enclosure.
Application
Use these protectors on low current mains power supplies,
e.g. CCTV cameras, alarm panels and telemetry equipment.
