Type S magnetic starters are used for full-voltage starting and stopping of AC squirrel cage motors. Motor overload protection for three-phase starter applications can be provided through one of four options, as follows:

• Solid-State Overload Relay Protection (Motor Logic™ SSOLR)

  These ambient insensitive overload relays are available on Sizes 00 through 6. They provide phase loss and phase unbalance protection. To order, add Form H30 (for selectable trip class 10 or 20 protection). For more information about Motor Logic SSOLRs, see Motor Logic and Solid State Overload Relay Factory Modifications (Forms). (Catalog no. example: 8536SCO3V06H30)

• Adapted Bimetallic or Solid-State Overload Relay (NEMA Sizes 00–1)

  The Adapted Bimetallic or Solid-State relay option includes a specially designed adapter that attaches with bus bars to the Type S NEMA contactor. This adapter allows direct mounting of the IEC Style bimetallic (LRD or LR3D) or solid-state (LR9D) overload relay. To order this starter configuration, add Form E (adapter only) to the standard catalog number. The LRD, LR3D, or LR9D overload relay must be purchased separately, based on the FLA of the motor, and installed in the field to properly operate the starter. For the Adapted Bimetallic device only, if the FLA is known at the time of purchase, you can order the starter with the overload relay installed. For more information and a list of options, see Adapted Bimetallic Overload Relay Forms. (Catalog no. example: 8536SCO3V06E—without overload relay).

• TeSys™ T Motor Management System (NEMA Sizes 1–6)

  TeSys™ T is a flexible system that integrates seamlessly into your automation system through five major communication protocols. TeSys T can predict what will happen in the process, as it accurately monitors current, voltage, and power over a wide range. For additional information about TeSys T Motor Management System, see TeSys™ T Motor Management System and Forms for FV Contactors and Starters. NOTE: The full catalog number contains a four-character Form number (for example, 8536SCO3V06H616).

• Melting Alloy Type Thermal Overload Relays (NEMA Sizes 00–6)

  Melting alloy type thermal overload relays utilize the use of replaceble thermal units. These thermal units must be ordered separately and installed to operate the starter. Thermal unit selection begins on Thermal Unit Selection. The catalog number includes no Form number (for example, 8536SCO3V06).

Type SB–SD starters

Capacitors are sometimes used in motor branch circuits to improve power factor. The Size 0–2 Type SB–SD starters listed in 3-Pole Polyphase—600 Vac Maximum—50–60 Hz 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 AWG solid or stranded wire. NEMA Size 3 and 4 starters have provisions for auxiliary connections as a standard. You must supply lugs as necessary.

The Type S starters with auxiliary load terminals can 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.
