IPG Decision Table - How to Order
The ordering code for IPG circuit protectors may be
determined by following the steps in the decision tables
shown here.
1
First Decision
The coding given permits a self-assigning part number but
with certain limitations. Units with mixed ratings,
combinations 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 protector for AC motor start or
high inrush applications, the peak amplitude and surge
duration should be specified for factory assistance in rating
selection.

Second Decision
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:
A It is recommended that power leads be soldered to protectors having
push-on terminals for current trip ratings above 10 amperes.
B The 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.
C All IPG protectors meet normal requirements for moisture and salt spray
resistance.
D UL 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.
E When “A” is specified in the sixth decision in conjunction with IPG-6 type,
metric screw terminals are supplied.

*Only one auxiliary switch is normally supplied on two and
three pole units. Switch is located in the right-hand pole
(viewed from terminal end) unless otherwise specified.
