Applications

• Locations where receptacles are used with stationary or
portable electrically operated devices such as:

— Lighting systems
— Conveyors
— Heaters
— Motor-generator sets
— Air conditioners
— Compressors
— Pumps
— Locations where damp or corrosive conditions exist

• Class II: classied locations such as:
— Process industries where there are dust hazards from

handling such products as our, grain and starch or any 
location where ignitable amounts of dust are present or 
amounts which would adversely affect performance

Features

• Energized receptacle contacts deeply recessed to reduce
danger of accidental touching.

• Style 2 (shell and extra pole) grounding.

• Spring door keeps dust out of receptacle when plug is not in
use. Screw cap also supplied.

• Brass contacts exert constant pressure along entire contact
surface and provide superior electrical contact.

• Contacts have beryllium copper wire springs.

• Plug mechanical cable clamps prevent strain on cables– they
meet or exceed UL strain relief pull-out requirements.

• Neoprene bushing compressed by cable collar prevents
entrance of water.

• Insulators provide superior dielectric and mechanical strength
and lowest arc tracking.

• 1-1/2 NPT tapped conduit openings; one top two bottom.

• Interlocked disconnect switch provides safe connect and
disconnect operation at 30, 60 or 100 Amp, 600 Vac maximum.
Two or three pole, non-fused motor circuit switch.

• Interlocked circuit breaker provides interlocked connect and
disconnect operation as well as short circuit and thermal time
delay overload protection.  DBR permits safe operation in Class
II and III only.

• To operate, insert plug (which automatically locks into
receptacle) and turn Breaker Handle to ”ON” position. To
remove plug, turn Handle to ”OFF” position, lift Plug Release
Knob and pull plug out.

• ACP and CPH plug ts Powertite™ Series hazardous location
and DBR receptacles.

Standard Materials

• DBR receptacles: copperfree (4/10 of 1% max.) aluminum
receptacle and mounting box

• CPH and ACP plugs: copperfree (4/10 of 1% max.) aluminum
housings

• Insulating blocks: ber glass reinforced polyester

Standard Finishes

• Receptacles, mounting boxes, cord connector housings and
caps: epoxy powder coat

Options

• For Group B version add sufx -GB to receptacle (Group B
version not suitable for NEMA 4, 4X).

• For GE  breaker, add -GE to receptacle. Contact your local
representative for availability and price.

• Molded case switch available on the 150 Amp versions, add
sufx -K to receptacle.

• Special Polarization: Prevents plug insertion in a receptacle or
connector wired for a different voltage. In installations where
there are different line voltages, the special polarization option
is desirable. This allows only plugs and receptacles wired for
the same line voltage to be mated together. The receptacle
or connector interior is positioned 22-1/2°, relative to the
polarization rivet, to the right (as specied) of standard, and
plug is polarized to correspond. This option can be added
to receptacles using the Powertite™ Plug. Add sufx -P4 to
receptacle or plug.

• For 2” feed-thru openings (one top, one bottom) add sufx -22
to receptacle.

• 1 N/O and 1 N/C Auxiliary Contacts. Add sufx -AUX.
