APPLICATION:
• Designed to supply three(3) phase, grounded electrical power to portable or fixed electrical equipment such as welders,
infrared ovens, batch feeders, conveyors and truck and marine docks.
• Designed to provide an interlocked receptacle for use in hazardous locations, as defined in the National Electrical Code
(NEC). In addition, the receptacle is designed such that a mating plug can only be engaged and disengaged when the
switch handle is in the "OFF" position.
• Ideal for use on shipping docks, ports, and other "ship to shore" applications.
• Suitable for use in locations that require a degree of protection from the elements indoors and outdoors (NEMA Type 3R
& 12) for the receptacle flip cover and (NEMA 3, 3R, 4, 4X and 12) for the receptacle screw cover.
• Enclosure cover is gasketted to seal cover against the enclosure housing.
• The receptacle face enables the engagement of mating plugs for a weatherproof union.
• MD2SR Series Interlocked Receptacle may be pole mounted or installed on flat vertical surfaces.
