arc-quenching, circuit interrupting-rated electrical plugs, motor
plugs, connectors, receptacles, mechanically inter locked receptacles
and assorted accessories. Usable in dry, damp, wet, marine and/or
hazardous locations for electrical power circuits. Devices are to be
rated 30, 60, 100, 200 and/or 400 amperes at 600VAC, 50–400
Hz and 250VDC maximum. Devices are also rated for continuous
use in temperatures from -40° C to +130° C. These devices must
provide internal environmental seals for marine and extreme wet
applications and can be electrically interlocked.

isolation and environmental separation.

disconnect under load shall have provision so the arc is contained
and extinguished within the insulation cavity, making it impossible
to withdraw a live plug.

provide weathertight capability by utilizing a spring actuated self­closing flap. Watertight capability shall be obtained by using a
gasketed screw cap.

voltage, frequency and phase; thus providing a single voltage rating,

through a separate center ground (earth) make-first and break-last
pole on all devices for complete system grounding.

catalog numbers as specified.

2.6 Pole Capabilities — All devices shall accom modate up to four

power pins plus a separate center ground pin and they shall be
integral with the connector bodies (five pins total).

2.7 Interior Type — Interiors must be male (pin type) or female

(sleeve type). Pins and sleeves shall also be self-aligning and
self-wiping/self-cleaning.

2.8 Control Contacts — All devices must have an option for two

control contacts, which shall be make-last and break-first for use
in electrical interlocks and/or control circuits. See table below.

2.9 Conductor Terminals — Pin and sleeve connections shall employ

solderless pressure-type screw terminals and be sized to accept
stranded or solid copper conductors in AWG sizes (max. O.D.s as
noted). The screw terminals shall also have socket heads to ensure
proper torquing of wires.

2.10 Environmental Seals — Each device must have an environmental

seal or O-ring around all interiors and around each pin and sleeve
to prevent water and contaminants from entering the wiring
compartment. This provides waterproof capability, even when
not mated.

2.11 Hazardous Location — All standard plugs 30, 60 and 100

amp shall be UL
Division 1, Groups C and D; Class II Division 1, Groups F and G.
A hazardous location circuit breaker-pro tected interlock shall also
be applicable to the same environments and possess all the same
product features as outlined above. Enclosures shall meet NEMA 8
hazardous outdoor-duty classifications and shall meet shipboard use
above deck in accordance with the Department of Transportation
(USCG “Green Water”).

2.12 Lockout Devices — Plug connection lockout is achieved

by a padlock through plug sleeve housing hole provided for
this purpose. On Hazardous Location/Explosion Proof Interlock
Receptacles, lockout shall additionally be achieved by separate
lockout accessory available from the factory. On standard
Interlocks, lockout accessory/construction is available from
the factory.
