HOW TO ORDER
The ordering code for the SNAPAK ? circuit protectors may be determined by following the steps in the decision tables shown here.
Push-To-Reset 2
Two Pole ?
Shunt Circuit Protector
Single pole (-1) and series only
Series w/ Silver Aux. Switch ???
when 1st decision "S" is
Thecodinggivenpermits
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.

???? Does not meet spacings for many IEC / VDE equipment specs.
Consult factory for additional information.
* Multi-pole units with mixed construction, poles numbered left to right when viewed
from terminal end. Shunt or relay construction available in pole 2 only, other pole must be a series
or switch only construction.
**UL 489A listed, available in 1 pole series or series w/silver aux. switch. DC delay only
T11 - 2- 5.00A - 01-11AL- V
CR, CPP, CPR only available in these delays
Todeterminetheordering
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.

3 Third Decision
Rated Current
Circuit Breaker Construction
Use three numbers to print required
current value between .100 amps
minimum and 30.0 amps maximum.
For example, use:
.100 or 2.00 or 10.0
Switch Only Construction
-SW Maintained SPST & DPST
Note: 20.0 amps max for 400 Hz units.
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.
