INTRODUCTION
The Airpax™ IPA/CPA hydraulic-magnetic circuit protectors
provide low-cost power switching, reliable circuit protection
and accurate circuit control for equipment in the international
marketplace.
IPA models meet IEC spacing requirements that are mandatory
for equipment which must comply with IEC specifications 601
and 950 and VDE specifications 0804 and 0805. In addition, they
are UL Recognized as supplementary protectors per UL STD.
1077, CSA Certified as supplementary protectors per CSA C 22.2-
No. 235, TUV Approved to VDE 0642 (EN60934), CCC Approved
(pending) and CE Compliant.
Designed using the latest in sensitive hydraulic magnetic
technology, the IPA line adapts itself to many applications and
environments. They’re ideal for data processing and business
machines, medical instrumentation, broadcast equipment,
vending and amusement machines, military applications
and wherever precision operation is required. Temperature
differences which affect fuses and other thermal devices are not
a concern.
One important feature of this protector line is a “trip free” action,
which means the circuit will trip in the presence of an overload
even though the handle is held in the ON position. The delay
mechanism senses the fault and the contacts open.
The IPA is available in configurations including series and series
with auxiliary switch, with a choice of delays and ratings in either
DC, 50/60Hz or 400Hz versions. Single or multi-pole versions
are available, with a variety of pole arrangements to meet your
specifications.

MULTI-POLE CIRCUIT PROTECTORS
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 IPA-11 with quick-connect D.I.N.-style terminals.
Individual poles may differ in ratings, delays and internal
connections. An auxiliary switch may be included in either or both
poles, allowing you to mix SELV and hazardous voltages. Rugged
screw-type terminals can be provided, in which case the
designation would be IPA-66. The IPAH offers a toggle handle for
each pole.
Three Pole Protectors
The three pole construction 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 for quick and convenient control, or if preferred, 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 IPA-666 for a three pole version.
Breaker poles are numbered consecutively when viewed from the
terminal side, with the ON position up, starting with Pole #1 on
the left side and proceeding to the right.
Handles
The IPAH two and three pole models are available with a handle
per pole.

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. In addition to providing
conventional overcurrent protection, the handle position
conveniently indicates circuit status.
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 breaker contacts, and will open regardless of whether
the breaker 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. An optional auxiliary switch, RS, configuration
allows an alarm or signal to be forwarded only upon electrical
overload, allowing for easier detection of fault circuit.

DC Delay Curves (typ)
DELAY CURVES - DC, 50/60HZ, 400HZ
A choice of delays is offered for DC, 50/60Hz and 400Hz
applications.
Delays 40, 59 and 69 provide fast acting, instantaneous
trip and are often used to protect sensitive electronic
equipment (not recommended where a known inrush
exists).
Delays 41, 51 and 61 have a short delay for general
purpose applications.
Delays 42, 52 and 62 are long enough to start certain
types of motors and most transformer and capacitor
loads.
Delays 400, 500 and 600 are long delays for special
motor applications.

SPECIFICATIONS
Trip Free
Will trip open on overload, even when the handle is forcibly held
on or restrained. This prevents operator from damaging the circuit
by holding the handle in the ON position.
Trip Indication
The operating handle moves positively to the OFF position.
Ambient Operation
IPA protectors operate in temperatures between
–40°C and +85°C.
Insulation Resistance
Not less than 100 megohms at 500 volts DC.
Dielectric Strength
IPA protectors withstand 3000Vac, 60Hz for 60 seconds between
all electrically isolated terminals except auxiliary switch terminals
shall withstand 500Vac, 60Hz for REG and REC types.
Endurance
Operating as a switch, the operating life exceeds 10,000
operations, at rated current, at a rate of 6 per minute.
Electrical Characteristics
IPA protectors are rated .050 to 30 amperes 65Vdc; .050 to 30
amperes 240 Vac 50/60Hz; 0.050 to 15 amperes 250Vac, 400Hz.
Poles
One through three poles available.
Construction
Series and series with auxiliary switch available in various delays
and combinations.
Auxiliary and Alarm Switch
When supplied shall be S.P.D.T. configuration with a maximum
rating of 3.0 amperes, 250Vac resistive load. Gold contacts are
rated at .100 amperes, 125Vac resistive load.
Moisture Resistance
Meet all the requirements of MIL-PRF-55629 when tested in
accordance with Method 106 of MIL-STD-202.
Salt Spray (Corrosion)
Meet the requirements of MIL-PRF-55629 when tested in
accordance with Method 101 of MIL-STD-202.
Shock
Circuit protectors shall not trip when tested per MIL-STD-202,
Method 213, Test Condition B with 100% rated current applied to
delayed units and 80% rated current to instantaneous units. Units
with auxiliary switches will withstand 30G max.
Vibration
Circuit protectors shall not trip when vibrated per MIL-STD-202,
Method 201, Test Condition A with 100% rated current applied to
delayed units and 80% rated current to instantaneous units.

Comparison of inrush pulse tolerance is with and without the
inertia delay feature for each of the 50/60 Hz 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.

HOW TO ORDER
The ordering code for IPA/CPA protectors may be
determined by following the steps in the decision
tables shown here.
Note:
A The coding given permits a self-assigning part number. Other configurations may require a
factory assigned part number. Typical examples are units with mixed ratings, combinations of
styles or construction. 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 exits to provide cross reference,
traceability and manufacturing control.
