System Overview

Eaton's new electronic overload relay (EOL) is the most
compact, high-featured, economical product in its class.
Designed on a global platform, the new EOL covers the entire
power control spectrum including NEMA
DP contactors. The NEMA and DP versions are offered with the
C440 designation while the IEC offering has the XT designation.
The electronic design provides reliable, accurate and value
driven protection and communications capabilities in a single
compact device. It is the flexible choice for any application
requiring easy-to-use, reliable protection.
Eaton has a long history of innovations and product
development in motor control and protection, including both
traditional NEMA, as well as IEC control. It was from this
experience that the C440 was developed, delivering new
solutions to meet today's demands.
C440 is a self-powered electronic overload relay available up
to 100A as a self contained unit. With external CTs, C440 can
protect motor up to 1500 FLA. Available add-on accessories
include remote reset capability and communication modules
with I/O for DeviceNet™, PROFIBUS
