reference 087/037285
Features and benefits
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
.
If several ESP 120-5A or 16A,
ESP 240-5A or 16A or ESP 277-5A
or 16A protectors are to be
installed together, or if one is in
use alongside Lightning Barriers
for video or signal lines, these can
be simultaneously mounted and
earthed on a CME kit and housed
in a suitable WBX enclosure (see
pages 263 & 264).
Accessories
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.
Installation
Use these protectors on low
current mains power supplies, e.g.
CCTV cameras, alarm panels and
telemetry equipment.
Application
47-63Hz
Ready boxed protector (here an ESP 240-5A/BX)
installed on the fused connection (spur) to an
alarm panel

ESP 277-16A). Note how the protector can
also be earthed from its earth stud
Connect in-line on supplies fused up to 5 A
(ESP 120-5A/BX, ESP 240-5A/BX or
