IAG4-39221-1 Datasheet, PDF (11/24 Pages) List of Unclassifed Manufacturers – Magnetic Circuit Protectors

CONFIGURATIONS
Series Trip
The most popular configuration for magnetic protectors is
the series trip where the sensing coil and contacts are in
series with the load being protected. The handle position
conveniently indicates circuit status. In addition to
providing conventional overcurrent protection, it’s
simultaneously used as an on-off switch.
Shunt Trip
The shunt trip is designed for controlling two separate loads
with one assembly. The control is established by providing
overload protection for the critical load. When the current
through this load becomes excessive and reaches the trip
point, the protector will open and remove power from both
loads simultaneously. The total current rating of both loads
must not exceed the maximum contact rating.
Auxiliary Switch (Applies to Series Trip Only)
This is furnished as an integral part of a series pole in
single or multi-pole assemblies. Isolated electrically from
the protector’s circuit, the switch works in unison with the
power contacts and provides indication at a remote
location of the protector’s on-off status.
Auxiliary switch contacts actuate simultaneously with the
main protector contacts, and will open regardless of
whether the protector contacts are opened manually or
electrically. For auxiliary switch ratings below 6Vac or
5Vdc, an auxiliary switch with gold contacts designated
as REG is available. Gold contacts are not recommended
for load current above 100 milliamps.

Note:
A: Terminal protrusion dimensions are referenced from back mounting panel.
B: Main terminals are male push-on type .250 [6.35] wide x 0.31 [.79] thick x .375 [9.53]
long or 8-32 x .187 [4.75] screw type. Metric screw terminals are M4 x 5mm (<=30A):
M5 x 5mm screw type (>30A). On VDE approved builds with screw terminals, external
tooth lockwashers are supplied. On VDE approved builds with push-on terminals a
soldered connection is required above 25 amperes.
