Curve 10
High Inrush — Time delays simi-
lar to Curves 1, 2 and 3 with
high-inrush surge capabilities.
Curve 100
High Inrush — For ferroreso-
nant power supplies, distribu-
tion transformers, data process-
ing equipment, etc., which may
draw starting surges as high as
3000% normal load. To accom-
modate brief surges of this
magnitude for approximately
a half cycle of line current, or
8.3 milliseconds (long enough
to get the equipment online
without tripping), high inrush
models are available.
Curve 30
High Inrush — Time delays simi-
lar to Curves 1, 2 and 3 with
high-inrush surge capabilities.
Curve 20
High Inrush — Time delays simi-
lar to Curves 1, 2 and 3 with
high-inrush surge capabilities.
EATON CORPORATION Technical Data
Specifications
All time-delay curves shown are
based on the fact that circuit
breakers are not preloaded.
(Breakers do not carry current
prior to application of overload
for calibration testing.) Curves
are plotted at an ambient
temperature of 77ºF (25ºC),
with breakers in the standard
wall-mount position.
Heinemann Breakers
are 100% Rated
All circuit breakers shall hold
100% rated load continuously.
Time-delay circuit breakers may
trip between 101% and 125%
of rated load; must trip at
125% and above, as shown on
the time-delay curve selected.
Breakers rated for ac/dc
operation may trip between
101% and 135%; must trip
at 135% and above.
Non-time-delay circuit breakers
may trip instantaneously
between 101% and 120% of
rated load; must trip instanta-
neously at 120% and above.
Ambient
Compensating
Time delay will decrease
as ambient temperature is
raised and increase as ambient
is lowered.
