Square D 8536SC03 Size 1 Starter 110 120 V Coil

Square D 8536SC03 Size 1 motor starter with a 110/120 VAC coil is a NEMA Type S electromagnetic starter designed for reliable on/off control of small to mid-size motors in industrial equipment. As part of Square D’s 8536 family, this Size 1 unit combines a magnetic coil and contact set in a compact package suitable for mounting in control panels and starter circuits, enabling straightforward field wiring for standard 110–120 V AC control signals. The 8536SC03 is commonly used in legacy machines and retrofit projects where a robust, serviceable starter is required, with compatibility for the common accessories and overload protection typical of 8536-series starters. This model’s identification by its coil voltage and Size 1 designation helps ensure it matches the motor’s full-load current within the 8536 catalog, and it is suitable for use in both 1‑phase and 3‑phase motor control applications in appropriate industrial environments. Typical applications include machine tools, conveyors, and other equipment lines in manufacturing settings that rely on durable, simple motor-start control, where a compact, field-reliable starter is preferred over more complex drive solutions.
