3ACT/3ACTR
SERIES
INSTALLATION
INSTRUCTIONS
Quick Start Guide
1. Mount the 3ACT/3ACTR Current Transducer to a
DIN rail or panel in a suitable enclosure.
2. With monitored load off, install each phase
through the sensing windows. Designate one
phase as A, B, and C.
3. Select the current range using the slide
switch
.
4. Connect output ter and - using 22-14
AWG copper wires rated 75/90
°
C. Tighten to 5-7
inch-pounds torque.
5. Connect power supply voltage to terminals 9-10.
6. The output will be proportional to the current in
each phase, plus one which is the average of the
three.
7. Any of the four analog signals can be used
independently, or all four can be used at the same
time.

CE
Warning! Risk of electric shock or
personal injury
Safe operation can only be guaranteed if
the
transducer
is used for the purpose for
which it was designed and within the limits
of the technical specifications. When this
symbol is used, it means you should consult
all documentation to understand the nature
of potential hazards and the action required
to avoid them.
Warning! Risk of hazardous voltage
When operating the transducer, certain parts
may carry hazardous live voltage (e.g., primary
conductor, secondary terminals). The transducer
should not be put into service if the installation is
not complete.
For products intended for the EU market, the
following is applicable to the CE compliance of
the product:
The 3ACT/3ACTR Series may comply with EN 61010-1 CAT III
300V max line-to-neutral measurement category. If insulated
cable is used for the primary circuit, the voltage rating of the
measurement category can be improved according to the
characteristics given by the cable manufacturer.
