INTRODUCTION
The APL/UPL magnetic circuit pro-
tector provides reliable, low-cost
power switching, circuit protection
and circuit control. The handle
opens and closes a circuit, under
normal load conditions, similar to
an ON-OFF switch. Upon over-
load, the internal mechanism trips,
opens the contacts and forcibly
returns the handle to the OFF
position. Since the protector is “trip
free,” the internal contacts will not
remain closed in the presence of
an overload, even though the
handle is held in the ON position.
The APL/UPL line offers many
configurations including series,
shunt and relay with a choice
of delays and ratings. APL/UPL
multi-pole assemblies are available
with a mix of current ratings,
delays and internal circuit
configurations.
While designed for industrial,
military and information processing
applications, the APL is suitable for
use in any situation where
precision operation is required.
Most versions of the APL family
are recognized by UL 1077 as
Supplementary Protectors and certified
by CSA 22.2 No. 235 as Supplementary
Protectorssignated with the UPL.
Additionally, many versions
of the UPL comply with the spacing
requirements covered by
IEC specifications 950 and 601
and VDE specifications 0642
(EN60934) and are VDE approved
and CE Compliant. Please contact
the factory for assignment of a
part number.
205/295 Dust Sealed Protector
Combining the proven mechanism of the APL/UPL circuit protector with a
unique case design, the 205 version provides increased voltage ratings
plus a dust proof enclosure.
All openings in the case (including arc blowout vent and handle)
have been sealed with resilient rubber or mylar. In addition, case sections
have been designed with tongue and groove construction to provide an
overlapping closure. These features make the 205 ideal for applications
in harsh environments where reliable protection is essential.
205 protectors have standard full load current ratings from 0.050
amperes to 100 amperes and voltage ratings to 65Vdc and 277/480Vac.
Like all Airpax magnetic protectors, the trip current rating is not affected
by ambient temperature.
The 205 is recognized by UL and certified by CSA under the Component
program. Non UL-recognized versions of this series are designated 295.

Multi-Pole Circuit Protectors
Multi-pole protectors are combined in an assembly with the
actuating handles linked and the trip mechanisms internally
coupled. A fault in either protected circuit opens all poles
simultaneously. Applications include use in two-phase circuits,
single-phase three-wire systems or in two or more related
but electrically isolated circuits. A mix of delays, ratings and
configurations is possible, with the series type having any
of the auxiliary switches listed. Combinations up to nine poles
are available.

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 indi-
cates circuit status. In addition to providing conventional over-cur-
rent protection, it’s simultaneously used as an on-off switch.
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 pro-
tector contacts are opened manually or electrically. For auxiliary
switch ratings below 6Vac or 5Vdc, an auxiliary switch with gold
contacts is available. Gold contacts are not recommended for
load current above 100 milliamps.
The contacts on our optional RS auxiliary switch will open
only in the event of an electrical trip of the circuit protector.
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 simul-
taneously. The total current rating of both loads must
not exceed the maximum contact rating.
Relay Trip
This permits the overload sensing coil to be placed in a circuit
which is electrically isolated from the trip contacts. The coil may
be actuated by sensors monitoring pressure, flow, temperature,
speed, etc. Other typical applications include crowbar, interlock
and emergency/rapid shutdown circuitry. Trip may
be accomplished by voltage or current, which must be removed
immediately upon tripping.
Dual Coil
Dual coil protectors provide remote shut down option and
normal overcurrent protection in the confines of a single
protector pole. This construction saves space by eliminating the
need for an additional pole for the voltage trip function.
Voltage Trip
Sometimes called “dump circuits” or “panic trip circuits,” these
units make it possible to open main power contacts with lower
power inputs from one or more sources. This configuration
is becoming increasingly more important for sensitive circuitry
and denser packaging in automation systems. Available in
series, shunt, relay or dual coil configurations.

Inrush Pulse Tolerance (typ)
The following table provides a comparison of inrush pulse
tolerance with and without the inertial delay feature for each
of the 50/60Hz delays. Pulse tolerance is defined as a single
pulse of half sine wave peak current amplitude of 8 milliseconds
duration that will not trip the circuit protector.
All trip curves and trip currents are specified with the
protector mounted in the normal vertical position at ambient
temperature of +25°C. Protectors do not carry current prior to

Delays 64, 65 and 66
Delays 64, 65 and 66 are the latest 50/60Hz delays with short, medium
and long trip times respectively. The patented protector design provides
both increased tolerance to high inrush induced nuisance tripping and
longer trip times at 600 percent. These delays are ideally suited for
applications where thermal devices are presently used, such as motor
protection or where short duration, high inrush currents are experienced.
As shown in a typical motor start-up curve, the delay 66 will provide
locked rotor and overload protection. Nuisance tripping is avoided since
acceptable short periods of overload will not trip the protector.

APL/UPL DECISION TABLES
How to Order
The ordering code for APL/UPL circuit protectors may be
determined by following the steps in the decision tables
shown here.
The coding given permits a self-assigning part number;
other configurations may require a factory assigned part num-
ber. Typical examples are units with mixed ratings,
combinations of styles or constructions not listed in the
third decision table, etc. With these, it is suggested that
order entry be by description and/or drawings and a part
number will be assigned. Additionally, it is a standard policy
to establish a factory assigned part number wherever a
descriptive drawing exists to provide cross reference,
traceability and manufacturing control.
When specifying a 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 code shown is the code for a two pole
UPL protector with series trip, 20 ampere rating, 50/60Hz.
short time delay construction in all poles.
To determine the ordering number for your particular
APL/UPL unit, simply follow the steps shown. You may use this
number to place an order or as a reference for further ques-
