Information
GJ1P Series
EATON CORPORATION Frame Information — GJ1P Series
Eaton Corporation’s Heinemann
GJ1P breakers offer high-quality
circuit protection for dc
applications from 100 to
1200 amperes.
Their precisely tailored time
delays and ability to interrupt
high currents makes them
ideally suited for critical applica-
tions. On overloads exceeding
1000 – 1400% of rating, there
is no intentional time delay and
the breaker interrupts currents
of as much as 100,000 amperes
at 65 Vdc up to 1200 amperes.
An optional shunt (25 or 50
millivolt full scale) permits
metering of current. Since the
shunt output is low voltage,
light-gauge wiring can be used
from shunt to meter. Indication
may be displayed in percent,
watts, safe/danger or other dial
calibrations. In addition, the bus
bar is available in two versions,
Standard Size and Reduced
Size. Contact your Eaton
sales representative for
more information.
Precision Current Equalization
(PCE) Circuit Breakers
GJ1P breakers rated 250
to 1200 amperes are built
in parallel construction.
Conventional parallel pole
breakers can experience
uneven current distribution
because of variations in internal
resistances. This condition
can result in nuisance tripping
since the higher current in one
parallel branch has the same
effect as an overload on the
sensing element in that branch.
Proprietary Precision Current
Equalization (PCE) circuit break-
ers, on the other hand, allow
for differences in internal resist-
ances by automatically distribut-
ing the current equally through
the parallel current sensing
elements, minimizing the
danger of nuisance tripping.
The UL listed series GJ1P
(UL 489) models are available
in a choice of fast, medium or
slow response times to accu-
rately match load conditions.
They can be ordered in “series
trip,” “mid-trip” and “switch
only” constructions and are
available front- or back-mounted,
front- or back-connected, with
optional auxiliary switches
for signaling.
