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 mechani*s. Conversely, an overload in either circuit
trips both simultaneously.
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 mechani* 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
*embly.
T*ical 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 *age specifications
and the wide gl* 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 *
designations. The AIRPAX cage code number is 81541.

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
