Typical Autotransformer Starter

Sizes 2–5

Separate Control (Form S)

note

Class 8606 starters come with a NEMA style medium-duty autotransformer.
Medium-duty service includes applications to motors that drive loads such as fans, pumps, compressors, and line shafts.
NEMA Sizes 2–5: Autotransformer is rated for fifteen 15-second starts per hour.
NEMA Sizes 6–7: Autotransformer is rated for three 30-second starts per hour.
Contact the Customer Care Center (CCC) at 1-888-778-2733 for applications that require frequent starting or jogging, or have extremely high inertia.

Footnotes

  1. NEMA 4 enclosures are painted sheet steel. Where required, stainless steel enclosures are available at extra cost.Specify as Form G17.
  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. No factory modifications (Forms) are available with the OEM. kit.
  4. Both the line and control voltage must be specified to order this product. See Specifications for the necessary codes and instructions for ordering.
  5. Specify Forms only if any of the coils are at a different voltage than line supply (V8•). See Specifications for a fuller explanation of how to order; this page also provides the necessary coil voltage and Form codes as well as codes for 380 V starters and 50 Hz applications.
