Applications:

BHR dead front interlocked receptacles and switches with BHP plugs are used:

• To supply power to portable electrical equipment such as motor-generator sets, compressors, heating and cooling units, lighting systems, conveyors, and similar equipment

• Primarily in areas which are hazardous due to the presence of hydrogen or gases, or vapors of equivalent hazard such as manufactured gas

• In damp, wet, or corrosive locations

• Indoors or outdoors in hydrogen areas of process industries, missile bases where hydrogen fuel is used, and gas manufacturing plants

Features:

• BHR receptacles feature a built-in rotary switch which is operated automatically when the plug is inserted and withdrawn.

The switch, capable of making and breaking the circuit at full rated load, is operated by a helical blade in the center of the plug

• The plug and receptacle contacts cannot be made or broken under load. When the plug is inserted, the plug and receptacle contacts engage before the switch closes. When the plug is withdrawn, the switch opens before the plug and receptacle contacts disengage. This sequence of operation provides maximum safety in a dead front receptacle. Arcing is isolated in a flame and dust-tight chamber

• Operation is simple, safe and positive. To disconnect the portable device, the plug fastening ring is unscrewed and the plug simply pulled straight out. No separate interlock device or operating handle need be actuated

• Positive engagement without mismatching is assured by a distinct physical polarization of the plug and receptacle in every rating

• Plugs are furnished with pressure terminations. Receptacles are furnished with flexible leads for splicing to the supply conductors. A large threaded cover provides access to the wiring compartment

• As shown in the listings, assemblies are available for top, bottom or through feed conduit arrangements in 3/4" to 2" sizes

Grounding:

• BHR receptacles and BHP plugs are provided with an extra grounding pole. In plugs, provision is made for attachment of the grounding wire to the grounding pole.

In addition, direct connection is provided between the plug and receptacle housings and the grounding pole. In the receptacle, grounding is accomplished through the conduit system

Standard Materials:

• Receptacle housings – copper-free aluminum

• Seals – malleable iron

• Plug exteriors – copper-free aluminum

• Insulation – high impact glass filled phenolic

• Contacts – brass

Standard Finishes:

• Copper-free aluminum – natural

• Malleable iron – electrogalvanized and aluminum lacquer

• Phenolic – natural (black)

• Brass – silver plated

Options:

• Special polarity – where two or more receptacles of the same ampere rating and number of poles are to be installed in the same areas for use on different voltages, alternate polarizations can be furnished. Details on request.

Electrical Rating Ranges:

• 30, 60 and 100 amperes, 480VAC

Certifications and Compliances:

• Class I, Division 1 and 2, Groups B, C, D

• Class II, Division 1 and 2, Groups F, G

• Class III

• NEMA: 3, 4, 7BCD, 9FG, 12

• ANSI/UL Standard: 1010

CAUTION: To reduce the risk of ignition of hazardous atmospheres, do not use plugs or receptacles in Class II, Group F locations that contain electrically conductive dusts.
