Full Voltage Starters—NEMA Rated
Class 8536 / Refer to Catalog 8502CT9701
Types SB–SD With Auxiliary Load Terminals
It is sometimes desirable to use capacitors in motor branch circuits to improve power factor. The Size 0–2 Type SB–SD starters listed below include three auxiliary terminals to allow easy connection of power factor correction capacitors. When capacitors are connected using these terminals, no adjustment to the selection of thermal units is necessary. The auxiliary terminals accept #12–16 solid or stranded wire. NEMA Size 3 & 4 starters have provisions for auxiliary connections. User must supply lugs as necessary.
The Type S starters with auxiliary load terminals may also be used to control two motors simultaneously from a single starter. However, this application is tightly restricted by Section 430-53 of the National Electrical Code. Refer to the NEC for restrictions regarding overload protection, size of controller and motor branch circuit protection.

Table 16.43:
c 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.
d 120 Volt Polyphase starters are wired for separate control and must be
ordered with Form S (i.e., 8536SCO2V02S).

For voltage codes used with control transformers, see page 16-111.
Form S (separate control) is used when a separate source of power is available for the control (coil) voltage.
Form S is supplied at no charge.
