SNAPAK® is a snap-acting
magnetic circuit protector that
combines power switching and
accurate, reliable circuit
protection in one aesthetically
pleasing package. 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 (page 51). Push-to-reset is supplied
with a contrasting color indicating shaft. In addition, SNA-
PAK® is offered in SPST and DPST configurations. The sin-
gle 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.
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 and CSA Certified, as
Supplementary Protectors per UL 1077 and CSA 22.2 No. 235 respectively.
They are also VDE Approved, CCC Approved and CE Compliant. In addition,
most versions 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.

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.

Series Trip

Single Pole Two Pole ( 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 accom-
plished by voltage or current, which must be removed after trip.

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 or relay configurations.
Power Switch
In the event that over-current protection is not desired, the coil
mechanism can be deleted, providing an excellent low cost
single or double-pole power switch. Maximum current rating
is 15 amperes.
Auxiliary Switch
This is furnished as an integral part of a series pole in single or,
multi-pole assemblies. Isolated electrically from the protectors cir-
cuit, the switch works in unison with the power contacts and pro-
vides indication at a remote location of the protector’s
on-off status.

Inrush Pulse Tolerance
Many circuit breaker applications involve a transformer
turn-on, an incandescent lamp load, or a capacitor charge
from a DC source. Each of these applications has one com-
mon 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).

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 VDE 0642 (EN60934) the SNA-
PAK® can perform 6,000 electrical operations. After any
endurance cycle, the protector will calibrate and have working
dielectric strength.

Notes:
AA 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 40mA. 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.
CWhen ordering Paddle Handles, you may choose one item from each
hardware group to add to 5th decision if such items are desired.
For example, “-11ALS” would indicate a bright nickel knurled nut, plus a
vertical mount indicator, plus a locking ring, plus #6-32 screw terminal
adapters. For Push-Pull, Rocker and Push-to-Reset versions, you may add
only the #6-32 screw terminal adapters (-S).
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.
DECISION TABLES
How to Order
The ordering code for the SNAPAK® circuit pro-
tectors may be determined by following the steps
in the decision tables shown here.
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 pro-
tector 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.

V = VDE and CCC Approved
The shaded areas denote VDE approval, CCC approval (if applicable) and CE compliant
options. This approval requires the addition of a V at the end of the part number. The V will
be added to any part number formed entirely from shaded decisions. If non-shaded areas are
selected, the unit will not be VDE approved, nor CE compliant, but other approvals still apply.
C = CCC Approved
This approval requires the
addition of a C at the end
of the part number. The unit
will not be VDE approved.
