Auxiliary Units

Auxiliary contacts and power poles can be added in the factory or the field on all Type S starters and contactors. Auxiliary Units—Class 8502 and 8536 shows the maximum number of auxiliary units, in addition to the holding circuit contact, that can be added to a given size starter or contactor. In addition, it is possible to add a second internal contact on NEMA Size 0, 1, and 2 contactors and starters.

Footnotes

  1. Stainless steel enclosures are shipped with hubs installed in the top and bottom of the enclosure.
  2. 24 V coils are not available on Sizes 4–7. On Sizes 00–3, where 24 V coils are available, Form S (separate control) must be specified (for example, order as 8502SBO2V01S).
  3. 120 V polyphase contactors are wired for separate control. Form S must be specified (i.e., order as 8502SCO2V02S).
  4. NEMA 12 enclosures can be field modified for outdoor non-corrosive and non–service entrance rated applications. See General Information .
  5. When adding four external auxiliary contacts to one Size 0 or 1 contactor, remove one of the return springs.
  6. NEMA 12 enclosures can be field modified for outdoor non-corrosive and non–service entrance rated applications. See for more information.
