CurrentWatch™ EAC Series Current Sensors
Powered AC Current Sensors, 24 VAC/DC,
Proportional Frequency Output
Instructions Publication

Effective July 2017
Introduction
The CurrentWatch™ EAC Series Powered
combines a current sensor and signal con-
ditioning electronics in a single package for
use in 24 VAC/DC control power applications.
The combination of these devices results
in a single unit with higher accuracy, fewer
individual terminations and a space-saving
simplified installation.
The EAC Series family of powered current sensors are available in
split-core enclosures with proportional frequency outputs. These
sensors are average responding and intended for use in constant or
on/off load applications with sinusoid waveforms.
Eaton’s current sensor family encompasses a broad range of prod-
ucts for cost-effective monitoring, status, and predictive mainte-
nance. Downtime and costly repairs can be avoided by utilizing
Eaton’s products and technologies in your control systems.
Quick Install Guide
The below steps can be followed to quickly install a CurrentWatch
EAC Series Powered sensor.
1. Run the wire to be monitored through the aperture.
2. Mount the sensor to a surface if needed.
3. Connect output wiring, using up to 12 AWG copper wires.
4. Choose the correct range by positioning the Range Jumper.
Installation
Considerations for all EACF Series models…
•
These sensors can be located in the same environment as
motors, contactors, heaters, pull-boxes, and other electrical enclo-
sures.
•
Mounting can be done in any position or hung directly on a wire
with a wire tie.
•
Be sure to leave at least one in. (2.54 mm) distance between sen-
sor and other magnetic devices.
•
Press the tab in the direction
shown in the diagram to the
right.
•
After placing the wire in the aper-
ture, press the hinged portion
firmly downward until a click is
heard and the tab pops out fully.
•
Keep split-core contact areas clean. Silicon grease is factory
applied on the mating surfaces to prevent rust and improve per-
formance. Be careful not to allow grit or dirt into the grease in
the contact area, particularly on core mating surfaces of split core
models. Sensor operation could be impaired if mating surfaces
do not have good contact. Check visually before closing.
Range Selection
The CurrentWatch EAC Series Powered sensors feature field select-
able ranges. The ranges are factory calibrated, eliminating time con-
suming and inaccurate field setting of zero or span.
Setting Range
1. Determine the normal operating amperage of your monitored
current.
2. Select the range this is equal to or slightly higher than the normal
operating amperage.
3. Place the Range Jumper in the appropriate position.
Output Wiring
Connect control or monitoring wires to the sensor. Use up to 12
AWG copper wire and tighten terminals to 4 in.-lbs / 0.45 N·m maxi-
mum torque.
Connection Notes:
•
Deadfront captive screw terminals,
•
Use 12-22 AWG solid or stranded,
•
Observe polarity.
