AP/UP, AP/MIL Series - Introduction

INTRODUCTION
The Airpax™ AP series are fully sealed, magnetic circuit
protectors that combine power switching and accurate, reliable
circuit protection with inverse time delays and trip free features.
Unlike a thermal circuit protector, the AP does not change its
trip current over a wide temperature span. In addition, the AP
magnetic circuit protector is available in either DC, 50/60Hz or
400Hz versions and with various delays to match the protector to
specific application requirements.
One of the most important features of this protector is the “trip
free” action, which means the circuit will not remain closed in
the presence of an overload even though the handle is held in
the ON position. The delay mechanism senses the fault and the
contacts open.
Waterproof panel integrity is provided by an “O” ring bushing
seal and a silicon rubber gland within the bushing/handle
assembly.
Typical applications include communication, navigation and
aircraft instrumentation, radar and power supplies.
The Airpax™ UP circuit protector, with UL recognition and CSA
certification, is essentially the same as the AP in construction
and operating principle. It is approved for operation at 50 volts
DC to 20 amperes, 120 volts 50/60Hz to 15 amperes and 240 volts
50/60Hz to 7.5 amperes. The UP circuit protector is available in
single pole units only, due to UL and CSA creepage specifications
and the wide glass terminals utilized.
The Airpax™ AP-MIL protectors are produced in accordance
with MIL-PRF-39019 and the pertinent specification sheets,
are subjected to an exacting production and test program to
maintain their Qualified Products Listing (QPL). One, two and
three pole series trip units, with or without auxiliary contacts,
have been accepted for this listing. Refer to specification sheets
MIL-PRF-39019/1 through 6 for the application government
designations. The AIRPAX cage code number is 81541.

SINGLE POLE CIRCUIT PROTECTORS
MULTI-POLE CIRCUIT PROTECTORS
AP Multi-Pole Combinations
Circuit demands and design ingenuity suggest a limitless number
of special combinations, ranging from a two pole unit with one
series breaker and a simple ON·OFF switch, to a more complex
three pole unit having one series, one shunt and one relay
configuration with auxiliary indicator circuit contacts. Please
contact Airpax for specific part number.
Two Pole, AP12
Two of the basic units are combined in a sealed case to provide
protection for dual circuit. A single toggle handle actuates both
internal trip mechanisms. Conversely, an overload in either circuit
trips both simultaneously.
The AP12 consists of two independent series trip protectors,
each available with its own rating and delay characteristics.
This two pole unit can therefore have an unlimited number of
combinations, which makes ordering by a code system
impractical. Thus, if the poles differ, a descriptive drawing is
recommended.
One frequent use of two pole protectors is to interrupt either or
both sides of a power line. Likewise, three pole protectors often
use three identical coils. However, any two or three pole
protectors may have any coil of any delay in any desired
combination. (Unless otherwise specified, we assume the two or
three poles to be all alike.)

combination. (Unless otherwise specified, we assume the two
or three poles to be all alike.)
All multi-pole units have provisions for a rugged three point
panel mount. Use of 6-32 panel seal screws together with the
bushing mount is recommended to maintain specification
shock and vibration levels.
Three Pole, AP112
Three circuits may be simultaneously protected. One actuating
toggle handle closes all circuits and all poles trip in the
presence of an overload on any circuit. Some typical
combinations could be: 3 series poles; 2 series and one shunt; 2
series and one relay; or 3 series with a set of auxiliary contacts.
Like the two pole protectors, each pole may have different
ratings and delays.

AP/UP, AP/MIL Series - Configurations

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 position conveniently
indicates circuit status. In addition to providing conventional
overcurrent protection, it’s simultaneously used as a power
disconnect.
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 immediately upon tripping.
Remote Indication, AP1-1R
AP series trip circuit protectors are available with electrically
isolated contacts which are rated at 1/2 ampere, 120 volts AC
or 50 volts DC. These contacts provide SPDT switching action
which can be used to indicate “power-on” and “power-off”
conditions or to actuate lights, alarms or timing devices.
Voltage 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.

Lever Strength
The operating lever or its seal will not be damaged by a 10 lb.
force applied in any direction.
Shock
All protectors withstand 100G without tripping, even while
carrying full rated current with shock applied in any plane
of 6 ms duration. Test is made according to Method 213, Test
Condition I or MIL-Std-202 as outlined in Paragraph 4.6.14 of
MIL-PRF-39019. Delay 40, 50 and 60 breakers are tested at 80%
of rated current.
Vibration
All protectors withstand vibration from 10 to 55 cycles at .06
double amplitude and 55 to 2000 cycles at 10G, applied in
any plane, without damage and without tripping even while
operating at full rated current. Test is made in accordance
with Method 204A, Test Condition C, of MIL-Std-202 as
outlined in Paragraph 4.6.12 of MIL-PRF-39019. Delay 40,
50 and 60 protectors are tested at 80% of rated current.
Short Circuit Capacity
When tested in accordance with the procedures of UL1077,
AP supplementary protectors have a short circuit capacity of
1000 amperes at 32Vdc, 120Vac, 240Vac, 60 or 400Hz. Parts
are recognized to UL1077 for type UP1 only. The rated Rupture
Capacity per MIL-PRF-39019 is 500 amperes, 50 volts DC, 500

AP/UP, AP/MIL Series - Decision Tables
85
HOW TO ORDER
The ordering code for AP magnetic circuit protectors may be
determined by following the steps in the decision tables
shown here.
For example, the following is the code for a two pole AP,
hook terminal, series unit, designed for operation in a DC
circuit. It has a short time delay and a rating of 20 amperes.
The coding given permits a descriptive part number, with
limitations. In the illustrated double pole example (AP12-1-
51-203), it is automatically assumed that both poles are
identical. One great virtue of magnetic circuit protectors is
their adaptability to complex circuits, thus variations from pole
to pole become the rule rather than the exception. Descriptive
drawings are recommended. In this event, factory assigned
part numbers are utilized.
To determine the ordering number for your particular AP
unit, simply follow the steps shown. You may use this
number to place a order or as a reference for further
questions you may have.
Notes:
A The UP has a wide glass terminal to meet UL
and CSA creepage specifications. Except as
completely non-standard there is no space for
more than two terminals and the UP is therefore
limited to only the single pole series circuit
configuration (Third Decision Table – 1). Delays
available in the UP are: 40, 50 and 60; 41, 51 and
61; 42, 52 and 62; 64, 65, 69, 71, 72 and 79.
B Users should refer to the applicable drawings of
MIL-PRF-39019. Configurations vary dependent
upon the revision of MIL-PRF-39019. The 6-32
threaded mounted bushings, useful for added
strength, are approved under this specification.
To assure that proper parts are received, consult
the factory for application assistance if there is
any doubt about which version is correct for the
application concerned.
C Screw terminals are available and are equipped
with standard terminal block. Space permits
their use only in the series configuration (Third
Decision Table ). Standard terminals are heavy
copper hooks.
D Screw terminals with SPDT auxiliary switch,
available only with the series circuit, may have
“R” soldering terminals, flattened and pierced, or
“RC” soldering terminals which are cane hooks.
Screw terminals (–7, –17, –117) are available
with SPDT auxiliary switch “R” type only.
E The nominal current values for 100% of rated
