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 I: classifi ed locations such as:
— Petrochemical plants
— Petroleum refi neries
— Paint and chemical plants
— Any location where ignitable vapors or gases are present
• Class II: classifi ed locations such as:
— Process industries where there are dust hazards from
handling such products as fl 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 to bottom.
• EBRH and DBR: 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. EBRH permits safe operation in Class I, Group B as well
as Class I, Groups C and D, Class II, Groups F, G, and Class III
(DBR in Class II and III only).
• EBR and DBR: interlocked circuit breaker provides interlocked
connect and disconnect operation as well as short circuit and
thermal time delay overload protection.
• 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 fi ts Powertite

EBR, EBRH and DBR receptacles.
Standard Materials
• EBR, EBRH and 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: fi ber glass reinforced polyester
Standard Finishes
• Receptacles, mounting boxes, cord connector housings and
caps: epoxy powder coat
Options
• For Group B version add suffi 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
suffi 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 specifi ed) of standard, and
plug is polarized to correspond. This option can be added
to receptacles using the Powertite
®
Plug. Add suffi x -P4 to
receptacle or plug.
• For 2" feed-thru openings (one top, one bottom) add suffi x -22
to receptacle.
• 1 N/O and 1 N/C Auxiliary Contacts. Add suffi x -AUX.
Certifications and Compliances
• UL Standard: UL 1010 (UL 1203), UL 894, UL 1682, UL 1686
