ELECTRA Metal Clad Plugs & Sockets: Construction- The casting is made from non-corroding die-cast aluminum alloy combining exceptional compactness with high strength. The design/construction eliminates the possibility of mismatch in fitting of plugs in corresponding sockets, The floating contacts in the sockets are self aligning and facilitates smooth plugging in without undue pressure (These can be easily removed for wiring ), A provision for pilot pin facilitates mechanical interlocking in case of 63A ratings Human Safety- Specially designed shroud to avoid accidental finger contact with plug-pins while inserting/removing the plug, Similarly, the contact tubes in sockets are deeply recessed to avoid human contact, The earthing pins ensure that earth connection is made first and broken last, being longer than conducting pins, The visible earth terminals facilitate easy checking of earth connection, The cable grip to the plug is made very strong by providing a compression gland and by protecting it at the point of entry by a strong rubber guard, Applications- Industrial, Commercial & Domestic portable equipments like Hand/Power Tools, Industrial Ovens, Welding Sets, Mobile Generators, Furnaces, Ships, Office Machines, Refrigerators, Coolers, Air-Conditioners, Overhead Cranes, Chilling Cabinets, Tile Polishers and Sewing Machines
