PRL4 Energy Sentinel
Energy Sentinel
The IQ Energy Sentinel is a submeter-
ing device that mounts directly on
a circuit breaker and monitors both
power and energy with an overall
accuracy of 99%.
This high system accuracy is achieved
by use of the Cutler-Hammer SURE
Plus Chip, which is a sophisticated
microprocessor.
All that is necessary to complete an
IQ Energy Sentinel installation is to
insert it into the load side of a breaker,
feed the load conductors through it,
and run the shielded twisted pair wire
for communications. The IQ Energy
Sentinel has a nonvolatile memory,
is powered by the circuit breaker,
and can be applied on 3-phase, 4-wire
or single-phase, 3-wire systems.
The space-saving design characteris-
tics of the IQ Energy Sentinel mean
they can be quickly and easily retrofit-
ted onto Series C circuit breakers
in existing equipment…with no addi-
tional space required. Additionally,
IQ Energy Sentinel can be installed
when upgrading to Series C from
older breakers that are physically
interchangeable…with no additional
space required.
Power and energy information from
IQ Energy Sentinels can be communi-
cated to a PC, a panel mounted Central
Energy Display (CED), or even existing
building management or distribution
control systems.

IQ Central Energy Display
The IQ Central Energy Display may
be panel mounted or located remotely
(up to 7500 feet [2286 m] away).
It displays power, peak demand,
and energy readings of up to 50 IQ
Energy Sentinels and eight IQ Data
Plus meters.
Additional capabilities include:
peak demand alarming, demand
and energy totals for groups of
IQ Energy Sentinels and IQ Data
Plus 11 digital meters.
Refer to your local Satellite for
retrofit and upgrade options available
for existing equipment.
