Example of the parts to order to build a complete GS or LK switch:

For example:

LK3SU3 (600 A nonfusible switch, use 15x15 shaft)
+ GS1AE6 (15x15 200 mm Type H shaft)
+ LK3AH150 (black/black, lockable)


To add auxiliary contacts:

For front-mounted contacts order
GS1AD30 (front-mounted auxiliary contact holder)
+ GS1AM110 (NO contact for GS1AD10, 20, 30)

  1. Shipped with line side terminal shrouds—for additional shrouds, see Terminal Shrouds. Terminal lug must be ordered separately—see Terminal Lugs.
  2. Obsolete.
  3. A GS1AN•• contact block may not be used on the same switch as a GS1ANT••. A single switch must use all GS1AN11/GS1AN22 contact blocks or all GS1ANT11/GS1ANT22 contact blocks.
  4. GS1 600–800 A and LK3 800–1250 A can receive 1 lug for 3 cables per terminal or 2 lugs for 2 cables per terminal.
  5. All GS1 and LK3 switches are provided with line side shrouding.
  6. Three-piece kit for either the line or load side.
