Personalized
Protection to Fit
Your Application
With advanced hydraulic-mag-
netic technology, we’re able to
match our breaker performance
to meet your exact application
requirements. Whether you
choose a standard curve, or
one of our special application
curves, we’re sure to have a
device that meets your needs.
In addition, if you have specific
requirements that can’t be met
with one of our off-the-shelf
products, we can custom
configure a breaker to protect
your equipment.
To find out more about custom
breaker solutions, or for applica-
tion assistance, you can contact
our Technical Resource Center
at 1-800-356-1243 or via email

Time Delay Curves and
Typical Applications
The curves shown indicate the
magnitude and duration of over-
loads, which will be tolerated
before tripping occurs. By
selecting the proper curve,
breaker response can
be closely matched to safe
operating limits of the equipment
or circuitry. The following are
standard curves for typical appli-
cations on ac and dc circuits.
Technical Data
EATON CORPORATION Technical Data
Curve 1
Allows the largest and most
prolonged overload needed to
prevent nuisance tripping on
motor circuits.
Curve 2
A medium delay accommodates
mixed loads consisting of lights,
motors and resistive heating,
where the breaker is rated to
the wiring instead of to any
specific load.
Curve 3
Permits a very brief time delay
period before tripping and is
used for protection of trans-
formers and electronic circuits.
Curve P
Non-time-delay breakers have
no deliberately imposed delay
and will trip instantaneously at
any load above 120% of
rated current.
