Motor-Generator Sets, Compressors, Heating and Cooling Units, Conveyors and Lighting Systems Applications

Feature a built-in rotary switch which is operated automatically when the plug is inserted and withdrawn, the switch, capable of making and breaking the circuit at full rated load, is operated by a helical blade in the center of the plugThe plug and receptacle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 withdrawnThe 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 tight and dusttight chamberOperation 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 actuatedPositive engagement without mismatching is assured by a distinct physical polarization of the plug and receptacle in every ratingPlugs 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 compartmentAssemblies are available for top, bottom or feed-through conduit arrangements in 3/4 to 2 in sizesCopper free aluminum receptacle housing material, malleable iron seal material, high impact glass filled phenolic insulation, brass contacts materialNatural copper free aluminum, electro-galvanized and aluminum lacquer malleable iron, natural (black) phenolic, silver plated brass finishReceptacles are supplied ready to install with a threaded capFeed-through hubs are standardReceptacles can be configured for top feed, bottom feed or feed-throughDust ignitionproof, raintight, wet locationsTo supply power to portable electrical equipment such as motor generator sets, compressors, heating and cooling units, lighting systems, conveyors and similar equipmentPrimarily used in areas which are hazardous due to the presence of hydrogen or gases or vapors of equivalent hazard such as manufactured gas1-1/2 in hub
