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
current (see delay curves) are those listed.
Other values can be readily supplied, in
general, without delayed delivery. For values
above or below the listed range, please consult
an Airpax sales office or sales representative.
F Consult factory for assigned part numbers.
