Footnotes

  1. Electrical interlock kit catalog numbers with “1” suffix indicate one normally open and normally closed contact; “2” indicates two normally open and two normally closed contacts. See Electrical Interlock Contact Ratings.
  2. 30–100 and 600 A Type DT, DTU (Series F) switches contain (2) separate switching mechanisms. Each mechanism will accept an electrical interlock. Some applications may therefore require (2) electrical interlocks.
  3. Double throw switches 92251, 92351, and 92451 are not available with factory or field installed electrical interlocks.
  4. Electrical interlock EK400DTU2 can be added to 200 A, 4-pole Type 82000 switches in the field.
  5. Type 82000 and DTU switches are available with electrical interlock factory-installed only. Not UL listed. Electrical interlocks are furnished with 2 N.O./N.C. contacts and are installed in both “ON” positions. To order, add suffix EI to standard switch catalog number.
  6. Neutral assembly catalog number DT200N can be added to 4P, 200 A, Type 82000 switches in the field.
  7. For 200 A Type 82000, a neutral assembly is available factory installed on 2P and 3P switches. Not UL Listed. To order, add suffix N to the standard catalog number. Neutral terminal lug data = (3) #4 - 250 kcmil Al/Cu wire and (1) #4 - 250 kcmil Al/Cu service ground.
  8. (3) 6-250 ground lugs are provided as standard. DS468GKD provides an additional (2) 6-250 ground lugs.
  9. Gaskets are provided.
