APG/UPG/IPG Series
Hydraulic Magnetic Circuit Protectors
INTRODUCTION
IMPORTANT NOTICE:
The APG/UPG is a legacy
product and no new design-in orders are being
accepted. If the specifications for this product are
necessary for your system, Sensata Technologies
recommends utilizing the Airpax™ IAG series.
The APG/UPG magnetic circuit protector provides low-cost
power switching, reliable circuit protection and accurate circuit
control in one complete package. It is intended for use in data
processing and broadcast equipment, vending and amusement
machines, military and marine applications, and wherever
precision operation is required.
Designed using a current sensitive hydraulic magnetic
principle, the APG/UPG adapts itself to many applications and
environments. Temperature compensations which affect fuses
and other thermal devices are not a concern. Nuisance tripping
is minimized.
The APG/UPG is available in a wide variety of configurations with
a choice of delays and ratings. In addition, it is available in either
DC, 50/60Hz or 400Hz versions.
Available in single or multi-pole variations, the APG/UPG comes
with a variety of actuators. To enhance front-panel aesthetics,
toggle or rocker actuated handles and caps are available in a
variety of attractive colors.
Multi-pole circuit protectors can be furnished with either single
or multiple actuators. In addition, a unique sealed, single handle
toggle version for harsh or military environments is available in
single or multi-pole configurations.
The UPG circuit protector is recognized under UL Standard 1077,
file numbers E66410 and E33504 as a supplementary protector.
It is also certified by CSA under CSA STD. C22.2–No. 235, file
number LR26229 as a supplementary protector. The APG is
qualified to MIL-PRF-55629.
APG/UPG circuit protectors are available in one through four
pole assemblies with a variety of pole arrangements, terminal
styles, and accessories to meet your specifications, including
APG/UPG adapter plate option to allow mounting in APL/UPL
cutout.
TWO POLE PROTECTORS
An assembly consisting of two single pole units, having their trip
mechanisms internally coupled, and with a single toggle handle,
forms the APG/UPG-11. It is also possible to provide a handle per
pole, which is referred to as UPGH11. Individual poles may differ
in ratings, delays and internal connections. An auxiliary switch
may be included in either or both poles if they are of the series
trip type. Screw-type terminals can be provided, in which case
the designation would be APG/UPG-66.

THREE POLE AND FOUR POLE PROTECTORS
The three pole structure consists of three single pole units
assembled with an internal mechanical interlock which
actuates all units simultaneously. A single toggle handle
operates all three poles, or a handle per pole is available.
The four pole structure consists of four single pole units
assembled with an internal mechanical interlock which
actuates all units simultaneously. A double toggle handle
operates all four poles, or a handle per pole is available. The
individual poles need not have identical characteristics and
any series trip pole may have an auxiliary switch. If screw-
type terminals are required, the breaker designation will be
APG/UPG-666 for a three pole version and APG/UPG-6666 for
a four pole version.
