EATON CORPORATION Application Information
Nuisance Tripping Eliminated
Heinemann hydraulic-magnetic
circuit breakers offer three
major advantages:
•
•
•
Guaranteed Power
Availability
Using a controlled time delay,
Heinemann circuit breakers can
eliminate nuisance tripping
caused by transient current
surges. In any installation
where a power supply or com-
pressor motor is on the line, an
inrush of current occurs when
the equipment is first turned
on. The bigger the equipment,
the larger the surge. Although
inrush surges are, in fact, tran-
sient overloads, they usually
pose no threat of damage to
the line or the equipment. So,
it’s simply not necessary or
even desirable to interrupt the
power when they occur.
The hydraulically controlled
time-delay mechanism of a
Heinemann breaker eliminates
nuisance tripping without reduc-
ing the overload protection.
The delay is inversely propor-
tional to the overload; response
is quicker on large overloads
where greater potential danger
exists, and slower on small
overloads. For sensitive elec-
tronic equipment, Heinemann
breakers can be purchased with
an instantaneous trip feature to
prevent damage.
Elimination of nuisance
tripping caused by high
ambient temperatures
in or near the installation.
The breaker responds only
to current variations, not
to temperature change.
Continuous operation at
100% current . There is no
such assurance with a ther-
mal device, which may fail
to carry rated current when
subjected to above normal
ambient temperatures.
A Heinemann breaker rated
at 20 amperes, for example,
will sustain 20 amperes,
even at elevated tempera-
tures. Derating and other
forms of temperature com-
pensation are unnecessary.
Immediate reset . Since
there are no thermal
elements, heat build-up
is not a factor. Therefore,
no “cooling off” period is
required after a fault.
Precision Protection
The current rating of the
hydraulic-magnetic circuit break-
er is determined by the number
of wire turns in the load sens-
ing coil. By altering the number
of turns and the wire size,
Heinemann can provide a
breaker of virtually any rating
within the unit’s overall current
carrying range. Regardless
of your needs, we can deliver
custom equipment protection,
even at fractional amperages.
Shock and Vibration
A precision, counterbalanced
armature design prevents
mechanical tripping due to
shock and vibration. This makes
the Heinemann family of prod-
ucts perfect anywhere shock
and vibration are a concern.
Some popular applications
include railcars, mobile industri-
al equipment, generators and
marine power distribution.
Global Ready
Heinemann breakers are tested
to meet global certifications and
standards including UL , CE,
VDE, TUV and CSA .
Mission Control
With a variety of control
and indicating options, the
Heinemann line of circuit break-
ers allows you to take control
of your complex operations.
Available with integral remote
trip coils and indicating con-
tacts, Heinemann breakers can
be integrated into your control
logic. We also offer a lighted
handle design that can allow
operators to see breaker
conditions at a distance.
Self-Adjusting
The time delay feature is
self-adjusting to ambient
temperature conditions. At
high ambients where the
overload tolerance of most
circuits is lowered, the viscosity
of the fluid in the breaker’s
dashpot is lessened, and the
time delay is thereby short-
ened. At low temperatures,
the response is correspondingly
longer to allow for cold equip-
ment startups.
