AP/UP, AP/MIL Series
Hydraulic Magnetic Circuit Protectors
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. Salt spray testing per MIL-STD-202, Method 101,
Test Condition B, with no evidence of corrosion, electrical or
mechanical damage.
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 UP series offers an
optional FM approval (Factory Mutual Research), provided for
petrochemical applications. FM approval is available for single
pole, series trip, UP type units only.
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.
