The CurrentWatch ECS Series from
Eaton’s electrical business is a family
of solid-state adjustable current
switches, ideal for providing status
information on electrical equip-
ment. 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 cur-
rents 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 con-
tact for switching AC and DC circuits
up to 240V AC/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 uncondi-
tional five-year warranty.
Any change in current can be sensed
with the ECS Series. A change in cur-
rent 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.
