SAFETY SWITCHES
[33] 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 Table
3.29 Electrical Interlock Kit, page 3-16 for electrical interlock ratings.
[34] 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.
[35] Double throw switches 92251, 92351, and 92451 are not available with factory or field installed electrical interlocks.
[36] Electrical interlock EK400DTU2 can be added to 200 A, 4-pole Type 82000 switches in the field.
[37] 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.
[38] Neutral assembly catalog number DT200N can be added to 4P, 200 A, Type 82000 switches in the field.
[39] 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.
[40] (3) 6-250 ground lugs are provided as standard. DS468GKD provides an additional (2) 6-250 ground lugs.
