Market Trends
Aircraft Original Equipment
Manufacturers (OEM) are
continuously pursuing
efficiencies associated with
the design and manufacture of
aircraft platforms. Additionally,
the OEM's are working on
increasing the functionality of
components while reducing
operating and life cycle costs.

ARC FAULT CIRCUIT INTERRUPT
The Aging Aircraft
Dilemma
Today, in the Unites States
there are more than 22,000
civil and military aircraft in
operation. Many are over 20
years old. To maintain airwor-
thiness, many have been ret-
rofitted with new engines,
new avionics, improved
hydraulic systems and even
new interiors. However, one
element in older aircraft that
will not change is the miles
and miles of electrical wiring
buried within the aging air-
frame. Over time these wire
bundles and their protective
insulation can deteriorate, pro-
viding the perfect environment
for an electrical short and a
potential fire hazard.
Until recently, aircraft circuit
breakers were considered the
first line of defense against
electrical hazards. However,
research has shown that arc
faults, with temperatures as
high as 6000°C, can go com-
pletely undetected by circuit
breakers developed over 30
years ago. The unfortunate roll
call of recent aircraft accidents
blamed on explosions or fires
suspected to have been trig-
gered by electrical wire arcing
is familiar. And the potential
for additional incidents may be
even more sobering. Safety
reports show numerous, non-
fatal incidents of smoke in the
cockpit and electrical faults
attributed to wire arcing.
Navy Statistics show 64 in-
flight electrical fires between
July 1995 and December 1997.
On the civil side, Federal
Aviation Administration (FAA)
data from 1989 through July
1998 show 622 reports of
smoke in the cockpit or cabin.
"No-Fault Design" By Rick
DeMeis, Design News
Sept 4, 2000.
Why Don't Aircraft
Circuit Breakers Provide
Protection from Arcing
Faults?
Aerospace circuit breakers are
designed to protect wiring
from thermal damage that
occurs during an over-current
situation. They are able to do
this by deploying a bi-metallic
element that mimics that ther-
mal effect of current on a
wire's insulation.
The reason circuit breakers do
not provide protection from
arcing events is that they are
not designed to. The character-
istics of an arcing event
include fault currents that are
sporadic or sputtering, have
values several times the
breakers rating, and the arc
event is of such a short dura-
tion that the circuit breaker
has little time to react.
Labinal Power Systems'
Arc-Fault Circuit
Interrupt (AFCI)
Technology - The Next
Generation of Circuit
Protection
"Present commercial airplane
circuit breakers do not detect
and react to arcing faults asso-
ciated with the chafing and
subsequent intermittent arcing
when bare wires contact
metal airplane structure or
other bare conductors…"
FAA Aging Transport Non-
Structural Systems Plan, July
1998, page 17 Incorporating
AFCI Into Thermal Protection
Devices
Labinal Power Systems' AFCI
protective device recognizes
the unique signatures of arc-
ing faults and acts to interrupt
the circuit. Labinal Power
Systems' Arc-Fault Circuit
Interrupt technology utilizes
microelectronics to monitor
and analyze a circuit's current
waveform. This logic circuit uti-
lizes algorithms developed
over the last 10 years. These
algorithms "look" directly for
the randomness in the 400Hz
current signal to determine if
an arcing event has occurred.
If the logic circuit determines
an arc fault exists, a signal is
sent to the circuit protection
device, which will safely shut
down the circuit in question.
Recognizing An
“Acceptable Arc” From
An “Unacceptable Arc" -
Elimination of the
"Nuisance" Trip
Labinal Power Systems'
unique AFCI technology moni-
tors the reaction of the current
waveform to an arcing incident
to ensure that the AFCI circuit-
ry can discriminate between
an unacceptable arc and an
acceptable arc. An unaccept-
able arc would be any situa-
tion such as two wires or a
wire to ground electrical arc
due to exposed conductors.
An acceptable arc could be
the power surge in the start-
ing of a hydraulic pump or
another electrically driven, pri-
mary or auxiliary support com-
ponent.
In order to distinguish an
acceptable arc from an unac-
ceptable arc, sophisticated arc
fault algorithms employ vari-
ous statistical methods that
are capable of identifying the
degree of chaos or random-
ness in the current signal. This
prevents the chance of nui-
sance tripping even in situa-
tions where the switching of
devices involves in-rush tran-
sients resulting from motor or
pump start-ups.
Integrating the AFCI circuitry
into the standard aerospace
circuit breaker required the
miniaturization of the present
mechanism to make room for
the necessary electronics and
to provide a way to power the
logic circuit. As a result of this
effort, Labinal Power Systems'
AFCI circuit breaker has many
added benefits:
• Offer same size as current
circuit breakers listed in
MS24571 and MS14105.
• Provides separate visible
indication of an arc fault vs.
over-current fault.
• Include independent
operation of the electro-
mechanical portion of
circuit breaker so that the
circuit breaker remains
operational even with an
AFCI electronics failure.
The AFCI technology can be
packaged into a form / fit line
replaceable unit (LRU) such as
a thermal circuit breaker.
Labinal Power Systems' AFCI
solution builds added safety
into the LRU without the need
to modify the existing electri-
cal architecture of the aircraft.
AFCI technology is easily
tailored t
o an application or
device. Labinal Power Systems'
product portfolio
of thermal
circuit breakers, relays,
and
Remote Control Circuit
Breakers
can provide the required
arc fault
protection to address every
platform electrical protection
requirement.

Performance Rated Circuit
Breaker
The lightweight, single-phase
circuit breaker, Series 4310,
allows high density packaging
for all aircraft and aerospace
needs.
The 4310 series reflects the lat-
est advancements in circuit
breaker design — plus other
proven features (e.g., self-wiping
contacts).
Tight tolerances in design and
stringent manufacturing stan-
dards are key factors in the reli-
able operation of the 4310 under
severe environmental conditions
of high temperature, high
humidity, extreme vibration, and
shock. It is also fungus- and cor-
rosion-proof.
Calibration integrity is main-
tained through wide variations in
ambient temperature and alti-
tude, making this circuit breaker
ideal for applications where tem-
perature is not controlled.
Multiple Options
This series is available in many
optional configurations.
It is presently being manufactured with 7/16,
15/32 and metric mounting sleeves. Many ver-
sions of different terminals, barriers, and hard-
ware are current production items. Several dif-
ferent actuator options provide our customers
with additional flexibility.

Heavy-Duty Three-Pole
High Performance
Three-phase protection of cir-
cuits from 50 to 100 amperes.
Interphase Insulation
Insulating interphase barriers
separate adjacent terminals.
Common Trip Bar
One bar connects the three
operating mechanisms for simul-
taneous trip action. Trip bar is
removable for installation.
Performance Rated Circuit
Breaker
The 940 series is the only three-
pole heavy-duty aircraft-type cir-
cuit breaker available in the 50 to
100 ampere range and consists
of three specially built 160-012
breakers with insulating inter-
phase barriers separating adja-
cent terminals. The unit has a
common trip bar connecting the
three operating mechanisms so
that an overload tripping one pole
will simultaneously trip the
remaining two poles.

SERIES 1526 FAST TRIP PROTECTION FOR DELICATE EQUIPMENT
Three-Pole High Performance
Common trip mechanism trips
all three phases, regardless of
which phase is overloaded.
Low-Current Protection
Protects circuits in ratings from
1 to 15 amperes.
Ambient-Compensated
Effects of temperature on trip
times are minimal.
Fast Trip
Operates on a hot-wire principle,
much faster than bimetal break-
ers.
Low Resistance
Contacts are made from a silver
alloy that maintains low resis-
tance throughout the life
of the breaker.
Load Protection
The fast tripping circuit breaker
is ideal for protecting sensitive
loads such as avionics and fuel
pumps where rapid detection
and fault clearing are desired.
Performance Rated Circuit
Breaker
The 1526 Series is the only hot
wire, fast-trip, three-pole circuit
breaker in ratings from 1 -15
amperes. A single actuator con-
trols all three poles, so that the
breaker can be easily operated
manually. There is only one over-
load latch; thus an overload on
one pole will open all three
poles simultaneously, regardless
of which pole is overloaded.
Long contact life is assured
through the use of a low-resis-
tance silver alloy.

Performance Rated Circuit
Breaker
This lightweight, miniature,
three-phase circuit breaker,
Series 4330, reflects the latest
advancements in circuit breaker
design, incorporating self-wiping
contacts, tight tolerances in
design, and stringent manufac-
turing standards. It is fungus-
proof and highly resistant to cor-
rosion. The trip-free thermal
mechanism avoids nuisance
trips (even during temporary
surges of starting loads) under
ambient temperatures ranging
from -55°C to +71°C. Calibration
integrity is maintained through
wide variations in ambient tem-
perature and altitude, making
this circuit breaker ideal for
applications where temperature
is not controlled.
Multiple Options
This series is available in many
optional configurations.
It is presently being manufactured with 7/16,
15/32 and metric mounting sleeves. Many ver-
sions of different terminals, barriers, and hard-
ware are current production items. Several dif-
ferent button options provide our customers
with additional flexibility.

REMOTE CONTROLLED CIRCUIT BREAKER (RCCB)
Qualified
Qualified to demanding perfor-
mance parameters of MIL- PRF -
83383 standard.
Use as a Relay, Circuit
Breaker, Or Both
RCCBs combine the best attri-
butes of a circuit breaker and a
relay. Automatically protects the
wires and the load device during
circuit/load breakdown, but
allows the flight deck control of
the load during normal opera-
tion.
Weight and Cost Savings
In distributed-load applications,
RCCBs are a more efficient
power distribution solution pro-
moting cost and weight savings
through the elimination of long
runs of heavy cables associated
with the conventional relay -
flight deck circuit protector
method. Control of the RCCB
requires only one #22 AWG con-
trol wire from the ICU on the
flight deck to the RCCB.
Cockpit Space Savings
An RCCB system removes the
presence of large circuit break-
ers from the cockpit while per-
mitting remote On/Off operation
from the flight deck. Combine
Labinal Power Systems RCCB
with Indicator Control Unit (ICU)
model #1500-053-05.

REMOTE POWER CONTROLLER (RPC)
Electronic Current Sensing
The electronic over current
sensing of these devices offer
several advantages over the bi-
metal sensing RCCB. Trip cur-
rent levels can be closely con-
trolled, for better protection of
sensitive loads, trip times are
faster, and both can be custom-
ized for specific applications.
Other advantages included less
heat buildup, and higher current
capabilities in the same small
package.
Use as a Relay, Circuit
Breaker, Or Both
RPCs, like RCCBs, combine the
best attributes of a circuit break-
er and a relay. Automatically
protects the wires and the load
device during circuit/load break-
down, but allows the flight deck
control of the load during nor-
mal operation.
Weight and Cost Savings
In distributed-load applications,
RPCs are a more efficient power
distribution solution promoting
cost and weight savings through
the elimination of long runs of
heavy cables associated with
the conventional relay - flight
deck circuit protector method.
Control of the RPC requires only
one #22 AWG control wire from
the ICU (model #1500-053-05)
on the flight deck to the RPC.

CIRCUIT BREAKER TERMINOLOGY GLOSSARY
Ambient
Compensation
Limits or eliminates thermal
derating (lowering of capabili-
ties) caused by extreme ambi-
ent temperatures.
Ambient Temperature
Refers to the temperature of the
air immediately surrounding the
circuit breaker/protection device.
Automatic Reset
Device that will automatically
open an overload circuit. It will
also automatically close or com-
plete the circuit after a period of
time. If the overload is still pres-
ent, the device will continue to
cycle until either the power or
the overload is removed.
Circuit Breaker
Device designed to open and
close a circuit manually and to
open the circuit automatically on
a predetermined overload of cur-
rent.
Current Rating
Designation of rating given in
amperes at which the device
will not trip. A specific tempera-
ture is usually assigned.
Dielectric Strength
The ability of an insulating mate-
rial to withstand an over voltage
without exceeding minimal leak-
age current levels or material
breakdown. Specified in voltage
(VAC), usually between a live
metal part and ground or
between open contacts of a
device.
Fuse
A protective device using a spe-
cial metal-alloyed conductor that
is often notched or otherwise
engineered to control the cross
sectional area. A fault current
will melt the narrow cross sec-
tion, interrupting the flow of cur-
rent.
Fusible Link/Fail Safe
A metallic sacrificial element
within the RCCB or circuit
breaker that melts and then arcs
due to the joule heating of an
over current. This feature
ensures that a fault cannot
cause the RCCB or circuit break-
er to fail in the closed position.
Interrupt Capacity
The highest level of fault current
that a circuit protective system
is intended to interrupt.
Depending on qualification
requirements, some devices
must clear the fault, be operable
afterwards, and still be capable
of tripping on 200 percent over-
loads. While other qualified
devices may have a backup
device wherein the combination
must successfully clear the fault
while leaving the protector in a
fail-safe condition (no loss of
case integrity, external materials
remaining unignited by gaseous
emissions, and no dielectric
path to grounded parts).
Manual Reset
Refers to breakers in which the
electrical contacts remain open
after a trip until someone physi-
cally closes or completes the
circuit by either pushing a reset
button or throwing a switch.
Maximum Ultimate Trip
(must trip)
Current rating at which a circuit
protection device will trip within
a certain period of time at a
specified temperature.
Minimum Ultimate Trip
(must hold)
Current rating for which a circuit
protection device will not trip for
an extended period of time at a
specified temperature.
Nuisance Trips
Those trips caused by a
response to non-damaging
inrush or start-up current surg-
es, as opposed to an actual
overcurrent trip.
Overcurrent
That current which may cause
dangerous overheating.
Overcurrent Protection
Protection achieved by limiting
the duration and magnitude of
exposure to an overcurrent.
Overload
An electrical load or current flow
greater than that which a circuit
is designed to handle.
Overload Capacity
The highest level of overload
current that devices will inter-
rupt and remain in operable con-
dition, capable of clearing addi-
tional overloads.
Safety Factor
The allowance added to the
steady-state application current
to ensure that the protective
device selected will be more
than sufficient to handle the
application without nuisance
trips. Labinal Power Systems
recommends a minimum safety
factor of 15 percent.
Slow-Blow Fuse
A dual element fuse that allows
for slow response to overloads
(less than 10x rating) and fast
response to fault currents.
Trip-Free
A characteristic of certain break-
ers that provides independence
between the protection mecha-
nism and the operating button
or handle, such that a fault can-
not be maintained manually (or
held closed) against an overload.
Trip Indication
Visual sign the breaker has
opened.
Trip Curve
Graphic displaying minimum and
maximum time a breaker takes
to trip for given levels of over-
load.
Voltage Drop
The voltage decreases across
the protector/breaker due to the
internal resistance of the device.
