IAG4-39221-1 Datasheet, PDF (20/24 Pages) List of Unclassifed Manufacturers – Magnetic Circuit Protectors

IAG/IUG/IEG/CEG DECISION TABLES
The ordering code for IAG/IUG/IEG/CEG/IDG circuit
protectors may be determined by following the
decision steps in the tables shown here.
The coding given permits a self-assigning part
number but with certain limitations. Special
applications may require a factory-assigned part
number. Typical examples are units with mixed
ratings, combinations of styles, or constructions not
listed in the third decision table. 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.
For example, the following is the code for a single
pole, IEG quick-connect type terminal, series unit
with auxiliary switch, designed for operation in a
50/60Hz circuit. It has a short time delay, a rating of
20 amperes, a black marked handle and is VDE
approved.
To determine the ordering number for your
particular IAG/IUG/IEG/CEG 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 circuit
protectors having push-on type terminals for current trip
ratings above 20 amperes.
B. When “A” (metric thread mounting) is specified in the sixth
decision in combination with screw terminal option in the
second decision, metric screw terminals are supplied.
C. IEG, IEGH, IEGS, IEGHS, IEGX and IEGZX circuit protectors are
designed to meet 8mm creepage and clearance requirements
for installation Category III, Pollution Degree 3, Case A as
measured in IEC 664. Intended for use in equipment designed
to comply with IEC 601 and 950 and VDE 0804
and 0805.

C = CCC Approved
This approval requires the addition of a C at the end
of the part number. The unit will not be VDE Approved.
V = VDE and CCC Approved
The shaded areas denote VDE and CCC (if applicable)
approval options. This approval requires the addition of a V
at the end of the part number. The V will be added to any
part number formed entirely from shaded decisions.
If non-shaded areas are selected, the unit will not be VDE or
CCC Approved, but other approvals still apply.
