Plugs and Switched Receptacles for Extreme Conditions

Meets demanding electrical requirements for hazardous locations

Satisfying the most demanding electrical codes, UPR Series plugs and receptacles simplify specification in oil refineries, offshore rigs, and other hazardous locations. Compact, lightweight and corrosion resistant, series is ideal for connecting power to portable or stationery electrical equipment, such as industrial lighting systems, heaters, conveyors, motor generators and pumps.


Both 16 Amp and 32 Amp UPR models are constructed of rugged non-metallic polyamide for superior corrosion-resistance, and provide critical safety features like color-coding to ensure safe identification of matching voltages, mechanical interlock so that disengagement cannot occur while energized, along with a keyed design to prevent insertion of plugs into receptacles wired for a different voltage or phase configuration.


Adding to operational safety is a lockable external switch that complies with IEC 60309-1, allowing the receptacle to be locked in either "on" or "off" position while giving visual confirmation of status to workers.


  • Plug and socket system is designed with a mechanical interlock to insure disengagement cannot occur while energized.
  • Large ON/OFF actuator on the receptacle gives clear, visible indication of the receptacle status for maximum hazardous location protection.
  • Receptacle can be locked in 0 (Off) and 1 (On) positions.
  • Different voltages are color coded for easy identification.
  • The receptacles are keyed to accept only UPR plugs of the proper voltage.
  • Receptacle is equipped with an explosion proof switch.
  • UPR plugs can be used in non-hazardous IEC 60309-2 sockets.
  • Operating temperature of -20 °C to +55 °C.
