breaker provides low-cost power
switching, reliable circuit protec-
tion and accurate circuit control
in one complete package. It is
intended for use in data processing
and broadcast equipment, vending
and amusement machines, military
and marine applications, and
wherever precision operation
is required.
Designed using a current
sensitive hydraulic magnetic
principle, the APG/UPG adapts
itself to many applications and
environments. Temperature com-
pensations which affect fuses and
other thermal devices are not a
concern. Nuisance tripping
is minimized.
The APG/UPG is available in a
wide variety of configurations
with a choice of delays and ratings.
In addition, it is available in either
DC, 50/60Hz or 400Hz versions.
Available in single or multi-pole
variations, the APG/UPG comes
with a variety of actuators. To
enhance front-panel aesthetics,
toggle or rocker actuated handles
and caps are available in a variety
of attractive colors.
Multi-pole circuit breakers can
be furnished with either single or
multiple actuators. In addition, a
unique sealed, single handle toggle
version for harsh or military
environments is available in single
or multi-pole configurations.
The UPG circuit breaker is
recognized under UL Standard
1077, file numbers E66410 and
E33504. It is also certified by CSA,
file number LR26229. The APG is
qualified to MIL-PRF-55629.
APG/UPG circuit breakers are
available in one through four pole
assemblies with a variety of pole
arrangements, terminal styles, and
accessories to meet your specifica-
tions, including APG/UPG adapter
plate option to allow mounting in

An assembly consisting of two single pole units, having their trip
mechanisms internally coupled, and with a single toggle handle,
forms the APG/UPG-11. It is also possible to provide a handle per
pole, which is referred to as UPGH11. Individual poles may differ in
ratings, delays and internal connections. An auxiliary switch may be
included in either or both poles if they are of the series trip type.
Screw-type terminals can be provided, in which case the designation
would be APG/UPG-66.

Three Pole and Four Pole Breakers
The three pole structure consists of three single pole units assem-
bled with an internal mechanical interlock which actuates all units
simultaneously. A single toggle handle operates all three poles, or
a handle per pole is available. The four pole structure consists of
four single pole units assembled with an internal mechanical
interlock which actuates all units simultaneously. A double toggle
handle operates all four poles, or a handle per pole is available.
The individual poles need not have identical characteristics and
any series trip pole may have an auxiliary switch. If screw-type
terminals are required, the breaker designation will be APG/UPG-
666 for a three pole version and APG/UPG-6666 for a four
pole version.
Breaker poles are numbered consecutively when viewed from
the terminal side, with the ON position up, starting with Pole #1
on the left side and proceeding to the right.

APG / UPG / IPG CONFIGURATIONS
Series Trip
The most popular configuration for magnetic protectors
is the series trip where the sensing coil and contacts are
in series with the load being protected. The handle posi-
tion conveniently indicates circuit status. In addition to
providing conventional overcurrent protection, it’s
simultaneously used as an on-off switch.
Shunt Trip
The shunt trip is designed for controlling two separate
loads with one assembly. The control is established by
providing overload protection for the critical load.
When the current through this load becomes excessive
and reaches the trip point, the protector will open and
remove power from both loads simultaneously. The
total current rating of both loads must not exceed the
maximum contact rating.

Relay Trip
This permits the overload sensing coil to be placed in a
circuit which is electrically isolated from the trip contacts.
The coil may be actuated by sensors monitoring pressure,
flow, temperature, speed, etc. Other typical applications
include crowbar, interlock and emergency/rapid
shutdown circuitry. Trip may be accomplished by
voltage or current, which must be removed after trip.
Auxiliary Switch
This is furnished as an integral part of a series pole in
single or multi-pole assemblies. Isolated electrically from
the protector’s circuit, the switch works in unison with the
power contacts and provides indication at a remote
location of the protector’s on-off status.
Vol tage Trip
Sometimes called “dump circuits” or “panic trip circuits,”
these units make it possible to open main power contacts
with lower power inputs from one or more sources. This
configuration is becoming increasingly more important
for sensitive circuitry and denser packaging in automation
systems. Available in series, shunt, or relay configurations.

Inrush Pulse Tolerance
It can be seen that the 64, 65 and 66 delays have a high inrush
capability and for most applications an inertia wheel would not be
required. Pulse tolerance is defined as a single pulse of half sine wave
peak current amplitude of 8 milliseconds duration that will not trip
the circuit breaker.
50/60Hz Delay Curves (typ)
A choice of delays is offered for DC, 50/60Hz, and 400 Hz
applications. Delays 40, 50, 60, 49, 59 and 69 provide fast-acting,
instantaneous trip and are often used to protect sensitive electronic
equipment (not recommended where known inrush exists). Delays
41, 51, 61 and 71 have a short delay for general purpose applications.
Delays 42, 52 and 62 are long enough to start certain types of motors
and most transformer and capacitor loads. Delays 43, 53 and 63 are
long delays for special motor applications at 400Hz DC and 50/60Hz.

APG / UPG DECISION TABLES
How to Order
The ordering code for APG/UPG circuit breakers may be
determined by following the steps in the decision tables
shown here.
The coding given permits a self-assigning part number but
with certain limitations. Units with mixed ratings, combina-
tions of styles, or constructions not listed in the third decision
table, require a factory-assigned part number. With these, it is
suggested that order entry be by description and/or drawings,
and a part number will be established. Additionally, it is
standard policy to establish a factory-assigned part number
whenever a descriptive drawing exists to provide cross
reference, traceability and manufacturing control.
When specifying a circuit breaker for AC motor start or high
inrush applications, the peak amplitude and surge duration
should be specified for factory assistance in rating selection.
For example, the following is the code for a single pole UPG,
quick-connect type terminal series unit with auxiliary switch,
designed for operation in a 50/60Hz circuit. It has a short time
delay and a rating of 20 amperes. A white handle is specified by
the seventh decision table.
To determine the ordering number for your particular
APG/UPG unit, simply follow the steps shown. You may use
this number to place an order or as a reference for further
questions you may have.
Notes:
AIt is recommended that power leads be soldered to
breakers having quick-connect terminals for current
trip ratings above 10 amperes.
BThe standard current values for 100% of rated
current are listed. Please consult an Airpax office or
sales representative for other values.
CUL recognized and CSA certified applications
above 30 amperes are restricted to loads having a
power factor of 75 minimum and limited to 32Vdc
only. Standard terminals on ratings over 30 amperes
are 10-32 screw type.
DFour pole breakers are available only in the
APGH/UPGH and APG/UPG types. The APGH/
UPGH four pole provides one handle per pole,
while the APG/UPG four pole has handles in the
center two poles only, for simplified mounting.
ESub panel mount available in APGX/UPGX
configuration only.
FWhen “A” is specified in the sixth decision in
conjunction with APG/UPG-6 type, metric screw
terminals are supplied.
GIf a circuit breaker is marked in this manner, it
means 277V per pole – single phase source. Thus, if
a two or three pole unit is marked 277V, all line
terminals must be connected to the same phase,
assuming the 277V is taken from line to neutral of
3 phase 277/480V system.

IPG DECISION TABLES
How to Order
The ordering code for IPG circuit breakers may be determined
by following the steps in the decision tables shown here.
The coding given permits a self-assigning part number but
with certain limitations. Units with mixed ratings, combina-
tions of styles, or constructions not listed in the third decision
table, require a factory-assigned part number. With these, it is
suggested that order entry be by description and/or drawings,
and a part number will be established. Additionally, it is
standard policy to establish a factory-assigned part number
whenever a descriptive drawing exists to provide cross
reference, traceability and manufacturing control.
When specifying a circuit breaker for AC motor start or high
inrush applications, the peak amplitude and surge duration
should be specified for factory assistance in rating selection.
For example, the following is the code for a single pole IPG,
quick-connect type terminal series unit with auxiliary switch,
designed for operation in a 50/60Hz circuit. It has a short time
delay and a rating of 20 amperes. Metric mounting inserts and
a white handle are also specified.
To determine the ordering number for your particular IPG
unit, simply follow the steps shown. You may use this number
to place an order or as a reference for further questions you
may have.

Notes:
AIt is recommended that power leads be soldered to breakers
having push-on terminals for current trip ratings above
10 amperes.
BThe standard current values for 100% of rated current are listed in
the fifth decision table. Please consult an Airpax office or sales
representative for other values.
CAll IPG breakers meet normal requirements for moisture and salt
spray resistance.
DUL recognized and CSA certified applications above 30 amperes
are restricted to loads having a power factor of .75 minimum,
and limited to 32Vdc only. VDE approval above 30 amperes is
restricted to 32Vdc and 120Vac 50/60Hz. Standard terminals on
ratings over 30 amperes are 10-32 screw type.
EWhen “A” is specified in the sixth decision in conjunction
with IPG-6 type, metric screw terminals are supplied.
