Widest full load amperes (FLA)
adjustment in the industry (5:1).
Adjustable trip classes (IEC Class
10A; NEMAT Class 10, 20 and 30).
Ground fault versions have only
NEMA Class 10 and 20.
Selectable (ON/OFF) phase
and ground fault protection.
Electronic remote reset /
communication modules
for easy competitive retrofit.
Predictive indication
The C440 and XT electronic
overload relays are designed
to provide enhanced protection
over competitive models. Traditional
self-powered electronic overload
relays rely on internal component
integrity to operate properly. If one
of these components should fail,
most relays would not provide any
operational indication. This could
leave a motor unprotected.
Relying on this passive approach
could result in significant equipment
damage and downtime. The C440
provides predictive indication via an
LED indicator. At a glance, you can
determine the status of the overload
as well as an impending trip to
provide enhanced protection of your
most important assets.
Single blink: Normal operation
Double blink: Fault condition developing
The electronic design of Eaton’s C440 electronic overload
relay delivers enhanced motor protection based on
the ability to directly monitor motor current in each
phase. Thermal modeling is performed electronically
with precision solid-state components. The electronics
accurately identify excessive current or phase loss and
react to the condition with greater speed, reliability and
repeatability than a traditional electromechanical device.
Flexible design
How do you know your overload is working?
