  • Standard maintenance or plant turnarounds to provide power connections for portable electrical products
  • Standard operation to provide a means of quick disconnect to move or disassemble equipment
Amperage 15 or 20A
Voltages 125 or 250V
Cord Range 0.39 - 1.20
Connector Body Material Copper-free aluminum
Environmental Rating NEMA 3R, Weatherproof


  • Uni-Shell™ handle body provides a smooth, durable external surface that prevents the connector from getting snagged on equipment or other cables
  • Spring-loaded sliding key offers increased safety: rejects standard NEMA/EEMAC configuration plugs that could cause an arc in a hazardous area; prevents the faceplate from being rotated until the ENP plug is fully inserted
  • Increased environmental reliability with hinged locking cover: provides weather protection in damp, wet, and dirty locations; cover stays closed until connection with ENP plug is required
  • Plug gaskets: two gaskets cover the entire range of cable diameters, reducing risk of improper assembly; gasket ratchets into Tri-Lock cable grip to prevent connector from turning or loosening
  • Improved safety with integral lockout/tagout eliminates risk of operator or contractor plugging in process equipment when conditions are unsafe
  • Saddle clamp terminals provide increased safety with easy-to-terminate connection points for reliable conductor terminations
  • Increased safety with captive Tri-Lock design: three points of contact prevent pinching of cables that could damage internal conductors or cable jacket; captive screws prevent critical components from getting lost during installation
  • Snap-in internal insulator increases safety of personnel with intermediate insulator between conductors and metallic outer shell
  • Mates with Eaton's Crouse-Hinds series frustration-free ENP Plug
