ECSJ Series CurrentWatch Current Switches
Product Description
The CurrentWatch ECSJ
Series current operated
switches from Eaton’s
Electrical Sector provide the
same dependable indication
of status offered by the
CurrentWatch ECS Series,
but with the added benefit of
increased setpoint precision.
A choice of three, jumper-
selectable input ranges
allows the ECSJ Series to be
tailored to an application,
providing more precise
control through improved
setpoint resolution. Self-
powering, isolated solid-state
outputs, 1–6A, 6–40A and
40–200A input ranges, and a
choice of split- or solid-core
enclosures are standard.
For typical applications of the
Current
Watch ECSJ Series,
see listing on this page.
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
●
