note

For voltage codes used with control transformers, see Factory Modifications (Forms).
Form S (separate control) is used when a separate source of power is available for the control (coil) voltage.
Form S is provided at no charge.

For dimensions, see Dimensions.

Refer to Digest Section 16 for factory modifications (Forms), replacement parts (Class 9998), and Type S accessories (Class 9999).

Footnotes

  1. Specify the speed that requires reversing by adding an L (low) or an H (high) after the type number—for example, a Class 8810 Type SBG21 with reversing in low only would be ordered as a Class 8810 Type SBG21L.
  2. NEMA Type 12 enclosures can be field modified for outdoor non-corrosive and non–service-entrance rated applications. See Digest Section 16 for more information.
  3. Replace the bullets (●●●) with the voltage code when ordering this product. Refer to the standard voltage codes shown in Coil Voltage Codes.
  4. Type numbers shown for three-phase, separate-winding motor starters apply only when motor windings are wye connected.
    When motor windings are connected open delta, prices for three-phase, consequent pole motor starters apply.
  5. 24 V coils are not available on Sizes 4–7. On Sizes 00–3, 24 V coils are available using Form S (separate control) (for example, order as 8810SCG21V01S).
  6. These voltage codes must include Form S (provided at no charge) (for example, order as 8810SDG21V02S).
