Model IQ 310:
❑ 110 – 240 Vac 50/60 Hz
❑ 125 – 250 Vdc
■ Model IQ 320:
❑ 90 – 600 Vac 50/60 Hz
❑ 48 – 250 Vdc
■ Models IQ 330 and IQ 330M:
❑ 90 – 600 Vac 50/60 Hz
❑ 48 – 250 Vdc
■
Optional I/O
The IQ 330 and IQ 330M models include
two digital inputs and two outputs
along with a single analog input. The
digital inputs can be used to show the
status of an external device on the
meter display and via communications.
Examples include breaker position,
motor starter status, protective relay
trip or any other device status. The
analog input accepts a standard 4 to
20 mA input, is shown on the display
from 0 to 100%, and is available
through communications. The analog
input can be used to read transformer
temperature, motor speed or any
analog process signal.
IQ 300
General Description
The IQ 300’s thin display and flexible
mounting capabilities make it perfectly
suited for any application where an
accurate, multi-function meter is
desired, such as panelboard and
switchboard mains and feeders, motor
control centers, and both low voltage
and high voltage metal-enclosed
switchgear.
One IQ 300 provides an alternative
to an assortment of individually wired
and mounted ammeters, voltmeters,
ammeter and voltmeter switches,
wattmeters, varmeters, power factor
meters, frequency meters, watthour
and demand meters. ANSI C12 Class
10 revenue metering accuracy makes
the IQ 300 an ideal choice for circuits
where precise energy measurements
are required.
The IQ 300 can be easily programmed
from the faceplate with display and
keypad which features a two-line
reverse mode LCD display with LED
backlight. Auto scrolling function
allows hand-free viewing of all voltages and currents. All measurements
can be viewed from the local display.
The IQ 300 can also be configured
and monitored using PowerPort ,
free software available on the Eaton
Electrical Web site, or can be used
with PowerNet, the full-featured
power management system software
(models IQ 320 and IQ 330 only).
The two digital outputs can be remotely
controlled via communications or can
be programmed in either of two different
alarm modes. In one mode, the output
will activate based upon the measured
system voltage and can act as either
an over- or undervoltage relay. The
second mode will enable the output
to alarm on a phase loss condition.

Meter Mounting
■
■
Bright display with eight large
numeric digits along with a 10character description of the measured value makes the IQ 300 ideal
for switchgear mounting.
■ Base unit can be display mounted
for simple, one-hole installation.
■ Base unit can be mounted up to
10 feet (3 m) away from display and
has three mounting options.
Ratings
■
Application to 200 kV, no PTs to 600 V.
CT ratios selectable from 5 to 8,000 A.
■ Three-phase, 3- or 4-wire.

Monitoring of electrical parameters.
Can be used on both low voltage
and medium voltage assemblies.
Metered/Monitored Parameters
■
The IQ 330 and IQ 330M models have
a hardware seal that prohibits the
changing of settings or the resetting
of values.
The base module can be display
mounted, panel mounted, DIN-rail
mounted or side-mounted. The display
only requires 1.50 inches (38.1 mm)
behind the panel it is mounted in,
including display to base cable.

Communications
The IQ 320 and IQ 330 models have
interface capability to computer network for data collection, storage and/or
printout via the Cutler-Hammer
PowerNet system.
The IQ 330M model has an industry
standard RS-485 multi-drop serial
interface with the Modbus RTU
communication protocol built-in. This
interface can be used to connect the
IQ 330M to a wide variety of Building
Management Systems, Programmable
Logic Controllers and other systems
utilizing this communication network.
