ECS Series CurrentWatch Current Switches
Product Description
The CurrentWatch™ ECS
Series from Eaton’s Electrical
Sector is a family of solid-
state adjustable current
switches, ideal for providing
status information on
electrical equipment. The
ECS is excellent for new
installations, where the
conductors run through the
housing, requiring no cutting.
These switches are also ideal
for retrofits, since split-core
models can be opened to fit
around existing conductors.
The current switch is
accurate, reliable and easy
to install.
The ECS can sense
continuous currents from
1 to 150A and does not
require any supply voltage,
as the power required is
induced from the monitored
conductor. The output is a
non-polarity-sensitive solid-
state contact for switching
AC and DC circuits up to
240 Vac/dc. This switch also
includes an LED indicating
two states: on and below trip
point, and above trip point
with contacts energized. All
ECS Series switches carry an
unconditional five-year
warranty.
Any change in current can be
sensed with the ECS Series.
A change in current may
indicate motor failure, belt
loss/slippage or mechanical
failure. Any of these events
can cause the current to drop
significantly, tripping the
switch and notifying the
controller.
Application Description
Typical Applications
●
Electronic Proof of
Flow—Current operated
switches eliminate the
need for multiple pipe or
duct penetrations and are
more reliable than electro-
mechanical pressure or
flow switches
●
Conveyors—Detect jams
and overloads
●
Lighting Circuits—Easier
to install and more
accurate than photocells
●
Fans, Pumps and Heating
Elements—Faster
response than temperature
sensors
●
Critical Motors
●
Ancillary Equipment
