INTRODUCTION
The Airpax™ SNAPAK® series is a snap-acting hydraulic-
magnetic circuit protector that combines power switching and
accurate, reliable circuit protection in one aesthetically pleasing
package. The SNAPAK® combines the functions of three
separate components: power switch, fuse and fuse holder. To the
OEM, this means that only one item has to be mounted instead
of three. Less assembly is required, inventory is cut by two-
thirds and greater panel density is obtainable with less clutter. In
addition, the SNAPAK® can be operated at either DC or 50/60Hz,
eliminating the need to specify, order and stock separate units.
400Hz units are also available.
To enhance front-panel aesthetics, SNAPAK® is offered with
paddle and rocker handles in six attractive colors and push-pull
and push-to-reset actuators. Also offered is a variety of optional
mounting hardware. The push-pull version is supplied with a
black button with a white indicating band.
Orientation of the button when marked with an amperage
notation must be specified when using the fourth decision table.
Push-to-reset is supplied with a contrasting color indicating
shaft. In addition, SNAPAK® is offered in SPST and DPST
configurations. The single pole satisfies most applications. The
two-pole version is often used for extra safety in products that
utilize high voltage or where current sensing and breaking of
both sides of the line is required. Quick connect terminals are
standard, UNC 8-32 or M4 screw terminals are available as
additional termination options.
Since the SNAPAK® is snap-acting, it assures immediate
opening and closing of the contacts. Its design also prevents
operator “teasing” of the contacts and minimizes arcing.
SNAPAK® circuit protectors are UL Recognized as
supplementary protectors per UL STD. 1077, CSA Certified as
supplementary protectors per CSA STD. C22.2 No. 235, TUV
Approved as circuit breakers for equipment per STD. EN 60934,
CCC Approved (customer must request product be manufactured
in China) and CE Compliant. In addition, most versions are
certified by UL to meet spacing requirements of IEC 950 for basic
and functional insulation for front panel mounting.
Consult factory for details and exceptions. Typical applications
include office appliances, electronic data processing, medical
equipment, business machines, vending and amusement
machines. Push-pull versions are particularly well suited for
medical instrumentation, automotive production transfer lines
and other applications where accidental turn off is unacceptable.
For those applications which do not require circuit protection,
SNAPAK® is offered in a power-switch-only configuration.

CONFIGURATIONS
Series Trip
The most popular configuration for magnetic protectors is the
series trip where the sensing coil and the contacts are in
series with the load being protected. In addition to providing
conventional overcurrent protection, it is simultaneously used
as an on-off switch.

( 1 pole shunt)
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 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 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 after trip.

OPERATING CHARACTERISTICS
Inrush Pulse Tolerance
Many circuit protector applications involve a
transformer turn-on, an incandescent lamp load,
or a capacitor charge from a DC source. Each of
these applications has one common factor: a
steep transient of very high current amplitude and
short duration. This takes the form of a spike or a
single pulse and is the cause of most nuisance
tripping associated with magnetic circuit
breakers.
SNAPAK® will withstand, without tripping, a single
pulse of 8 milli-seconds duration (half sine wave
configuration) and peak amplitude of 9 times its
rating without the inertia wheel and 13 times its
rating with an inertia wheel. (Not applicable to
instant trip delays).

DELAY CURVES & SPECIFICATIONS
400 Hz, DC, 50/60Hz Delay Curves (typ)
A choice of delays is offered for DC, 50/60Hz and 400Hz
applications. Delays 0, 49, 59 and 69 provide fast-acting,
instantaneous trip and are often used to protect sensitive
electronic equipment (not recommended where known inrush
exists). Delays 1, 41, 51 and 61 have a short delay for general
purpose applications. Delays 2, 42, 52 and 62 are long enough to
start certain types of motors and most transformer and
capacitor loads.
Trip Free
Will trip open on overload, even when forcibly held on.This
prevents operator from damaging the circuit by holding handle
in the ON position.
Trip Indication
The operating handle moves forcibly and positively to the OFF
position on overload.
Ambient Operation
Operates normally in temperatures between –40° C and +85°C.
Insulation Resistance
Not less than 100 megohms at 500Vdc.
Dielectric Strength
Withstands 1500 volts, 60Hz for 60 seconds or 1800Vac for one
second between all electrically isolated terminals.
Endurance
Mechanical life in excess of 50,000 operations. In many
applications, however, contact wear due to the electrical load
determines unit life. At maximum electrical ratings, the
SNAPAK® can perform 10,000 operations at rated current and
voltage. Under UL 1077, the SNAPAK® can perform 50
operations at 150% of maximum rated current followed by 6,000
operations at maximum rated current. Under EN60934 the
SNAPAK® can perform 6,000 electrical operations. After any
endurance cycle, the breaker will calibrate and have working
dielectric strength.

The family of protectors has been evaluated for end use application for use group (UG) A
The terminals (FW) are suitable for factory wiring only (0)
The maximum voltage ratings for which the protectors have been tested are shown in the chart
The current is the amperage range that the protectors have been tested
The tripping current (TC) for the protectors is either “1” (in the range of 125% to 135% of ampere rating) or “2” (more
than 135% of ampere rating)
The overload rating (OL) – designates whether the protector has been tested for general use or motor starting applica-
tions.
0 – tested at 1.5 times amp rating for general use
1 – tested at 6 times AC rating or 10 times DC rating for motor starting
The short circuit current rating (SC) – The short circuit rating in amperes following a letter and number designating the
test conditions and any calibration following the short circuit test is defined below:

Frequency & Delay
The coding given permits
a self-assigning part
number, with certain
limitations (due to the
adaptability of magnetic
protectors to complex
circuits), requires a
factory-assigned part
number.
The example shown is the
code for a paddle handle,
single pole (UL
construction), series
circuit protector designed
for operation of a 50/60Hz/
DC circuit. A slow time
delay and rating of 5
amperes has been
indicated. Handle color is
black, and a bright nickel
knurled nut, vertical mount
(ON-OFF) indicator plate
and locking ring are to be
supplied.
To determine the ordering
code for your particular
SNAPAK® unit, simply
follow the steps shown,
then fill in the letters and/
or numbers in the boxes.
Space is available on the
circuit breaker label for
your part number (up to 12
digits). You may then use
your own part number to
place an order or as a
reference for further
questions you may have.
This option does require a
factory assigned part
number for traceability to
your drawing or internal
part number.
Notes:
A A neon bulb is provided when specified for 120Vac and 250Vac operation. For operation
at 120Vac a 33,000 ohm, 1/2 watt external resistor is required. At 250Vac a 100,000
ohm, 1 watt external resistor is required.
B An LED with 750 ft. L @ 20mA is provided in the center of the handle. Maximum power
dissipation @ 25°C is 135mW. Continuous forward current is 20mA. Forward voltage,
typical, is 1.6v at 20mA. Reverse current, typical, is 100mA @ 3.0 volts. An external
resistor may be required to limit current to these values.
C When ordering Paddle Handles, you may choose one item from each hardware group to add to 5th
decision if such items are desired. For example, “-11ALCA” would indicate a bright nickel knurled nut,
plus a vertical mount indicator, plus a locking ring, plus #8-32 screw terminal, straight with tabs.
D All units except Rocker units will have (1) hex nut installed as standard hardware for the back of a
panel. The choices in the fifth decision table are intended for the front or visible side of the panel and
are offered for Paddle Handle configuration only. Push-Pull and Push-to-Reset configurations include
one (1) panel nut and one (1) hex nut as standard hardware.
E Switch only — no current overload protection provided.
F. CCC Approval - If CCC is required on this product, please inform Sensata to have this product
