ZoneSentinel Series

100kA surge capacity for distribution boards and small service entrance
locations

The ZoneSentinel Series is engineered
specifically for application at distribution
boards and small service entrance locations.
ZoneSentinel devices provide cost effective,
high capacity power surge protection and,
when used at a local panel in combination
with a ZoneMaster at the service entrance,
provide the lowest suppression voltages
available today.

ZoneSentinel units offer a 100kA surge
handling capability with protection be-tween

Line to Neutral, Line to Ground, Line to Line
and Neutral to Ground and no restriction to
the amount of load current. Thermal and short
circuit fusing mechanisms are also included
as an additional safety feature.

ZoneSentinel is modular in construction
with individual modules bolted to a large surge
return plate to minimize transient impedance.
These modules, with a UL 94-5 rated plastic
casing, are supplied mounted within a durable,
corrosion resistant, NEMA 4X rated enclosure
which can easily be drilled for cable access.
ZoneSentinel units are easy to wall mount and
flush mounting is also an option, should this
be required. Individual modules are available
upon request.

LED status indication is supplied with
ZoneSentinel units as standard - normally
open/normally closed contacts change state
to indicate a fault. These contacts can be
employed in a variety of applications from
turning on lights remote from the surge
protector, to interfacing with intelligent
building management systems.

An optional remote monitoring unit
is available for the ZoneSentinel range,
capable of monitoring the status of all panel
mounted surge protectors in the facility. This
unit provides audio and visual indication
of protector status in one compact wall
mounting case. Other features of the remote
monitoring unit include a test switch which
checks the monitoring circuitry and an audio
alarm silence switch.

The optional power filter, for the Type 2
ZoneSentinel range, which is tested to ANSI/
IEEE C62.41 and is UL 1283 listed, has a
noise attenuation of just 75dB at 100KHz to
100MHz. The filter module will attenuate 6kV
transients down to a mere 200V without the
support of other surge components.

All ZoneSentinel units are UL 1449 3rd
Edition Listed. Models with 20kA I

meet UL96A Master Label requirements.
