Applications:
Arktite circuit breaking plugs and
receptacles are used:
• To supply power to portable electrically
operated devices such as motorgenerator sets, compressors, heating
and cooling units, welders, conveyors,
lighting systems and similar equipment
• Where temporary power is needed, such
as at trailers, building units, heavy
machinery and similar equipment
• Wherever electrical loads must be
quickly disconnected from power source
• In a typical installation, where a large
machine utilizes a number of electrical
motor drives and for ease of adjustment,
removal, maintenance and replacement,
each motor is connected by portable
cord and Arktite receptacles rather than
permanently wired
• In areas where dust, dirt, moisture and
corrosion are a problem
• Indoors and outdoors in non-hazardous
areas of chemical plants, process
industry facilities, meat packing plants,
manufacturing plants and similar
industrial locations
Features:
• Circuit breaking: plugs through 100
ampere rating may be disconnected
under load; 150-400 ampere units are
for service disconnect use only.
• Receptacles accept only plugs of the
same amperage rating, style and
number of poles, making it impossible
to mismate, and provides for positive
polarization.
• Extra wide electrical spacing allows for
maximum safety.
• Insulator materials are the result of
intensive testing. Selection has been
made based on highest dielectric
strength, maximum mechanical and
impact resistance, lowest moisture
absorption and highest arc tracking
resistance.
• A variety of installations is possible due
to the availability of several types of
back boxes.
• Designed to withstand rough usage and
the effects of adverse environments.
• Reversible interiors, 30, 60 and 100
ampere (except 30 and 60 ampere,
5-pole) Arktite plug and receptacle
interiors are interchangeable using a
screwdriver. This makes it possible to
feed a normally de-energized receptacle
from an energized plug with usual Arktite
safety; no energized contacts are
exposed.
Certifications and
Compliances:
• UL Standards: 1203*; 1682, 1686
• CSA Standard: C22.2 No. 182.1

Split Pin Contact Design:
• Provides nearly 360° of contact at
every insertion, ensuring protection
against heat rise and eliminating
arcing on critical surfaces
• Continuous contact over length
and circumference of mated pins
provides superior safety and longterm performance
• Self-wiping at every insertion to
prevent environmental
contamination build-up
• The additional features below are
called out in the illustration on this page

The Tri-Lock™ cable grip has 3-piece design
9
that equally distributes gripping power around
perimeter of cable. Cord jacket does not get
pinched, eliminating potential for damage to
both internal conductors and external cable
jacket. Cable grip is located inside plug
housing, eliminating corrosion of vital
hardware and making plug maintenance easy.
The unique Sure-Seal™ cable gland has two
10
gasket sizes which fit entire range of cable
diameters, reducing risk of improper
assembly. The gasket ratchets into the Trilock™ cable grip to prevent plug from
turning or loosening in high vibration areas.
Wrenching surfaces make Arktite plugs
11
quick and easy to assemble
Smooth and contoured design of plug
12
housing eliminates occurrence of cable grip
snagging or breaking off. Tri-Lock™ screws
are captive so cable grip cannot come apart
during assembly. Prevents critical screws
from getting lost during installation.
Plastic sleeve between insulator body and
13
housing minimizes possibility of electrical
shock in event of ground failure. Increases
creepage and clearance protection.

Grounding: Style 1 vs. Style 2
Eaton's Crouse-Hinds Arktite devices utilize two methods, or styles, for completing the grounding circuit in plugs and receptacles. NEC
reference 250.138 (A) & (B).
Style 1 – Metallic
A Style 1 plug is one in which the
grounding conductor in the flexible cable is
bonded to the plug sleeve by a pressure
connector. A Style 1 receptacle is one
which is grounded by virtue of the fact that
it is an integral part of a grounded conduit
system. On insertion, the plug sleeve
makes contact with detent springs of the
grounded receptacle housing before line
and load poles engage, and on withdrawal,
remains in contact until after line and load
poles disengage. Therefore, exposed metal
parts of the portable equipment or plug are
suitably grounded.
Style 2 – Metallic
A Style 2 metallic housing plug is one in
which the grounding conductor in the
flexible cable is bonded to the extra
(grounding) pole and metal plug sleeve by
a pressure connector. A Style 2 metallic
housing receptacle is one in which the
extra (grounding) pole is electrically
connected to the equipment grounding
conductor and the metal receptacle
housing which itself is grounded by virtue
of the fact that it is an integral part of a
grounded conduit system. In Style 2, nonmetallic housing plugs and receptacles, the
extra pole is used for grounding since the
housings are non-conductive.
Style 2 – Non-metallic
In a Style 2 receptacle, the grounding
connection is made before line and load
poles engage, and is broken after the line
load poles disengage. Furthermore, upon
insertion, the plug sleeve of metal shelled
units makes contact with detent springs of
the grounded receptacle housing before
line and load poles engage, and on
withdrawal, remains in contact until after
line and load poles disengage. Therefore,
exposed metal parts of the portable
equipment or plug are suitably grounded.

Arktite receptacles have a cast raised
rib located inside the receptacle sleeve.
The location of the rib is in a specific
relationship to the receptacle insulator
that houses the contacts.
The mating plug has a cast groove
located on the outside of the plug
sleeve. This groove lines up with the
raised rib.

§150A, 200A and 400A rated units are for service disconnect use only.
† Horsepower ratings are based on Eaton's Crouse-Hinds testing in which locked-rotor currents were interrupted by withdrawing the plug from the receptacle. It is highly
recommended, however, that such use be limited to emergency conditions only, and that a horsepower rated switch be used for motor disconnect.
* This guide is for reference only. Consult your local electrical codes before installation.
✠ Eaton's Crouse-Hinds does not recommend our plug and receptacle be used for disconnect under load.
**Smaller sizes may be used with well reducers – information available upon request.
‡Do not use wire size smaller than minimum size recommended.
