Square D 9999SA2

9999SA2 is Square D’s Start/Stop push-button kit (Button Accessory Kit) for NEMA motor starters and contactors, Type S, designed for use with Square D starters in Type 1 enclosures across NEMA sizes 00 through 4. The kit includes a push-button unit, a wiring harness, a warning label, and a wire clip, with the wire clip provided for hinged-door enclosures. It provides local Start/Stop control of a motor starter, using color-coded actuators (black for one function and red for the other) to clearly distinguish run and stop operations, and it is compatible with Square D/NEMA motor starters in the 0–4 size range for panel installations. Rated for NEMA 1 enclosures, this accessory is a straightforward way to add manual control to motor-start circuits in industrial control panels. Part number 9999SA2.
