Schneider Electric 8536SBO2 Industrial Motor Starter

Schneider Electric's Square D 8536SBO2 NEMA Type S motor starter is a nonreversing, three‑pole open starter (Size 0) with an integrated Motor Logic overload relay for protecting and starting small three‑phase motors. It is rated for 18 A and 5 HP at 460 VAC, with coil voltage variants including 120 VAC or 240 VAC depending on the model, and it uses melting alloy overload elements for thermal protection. Some variants support Form S control with the option of a separate control power source for the coil voltage when a second power source is available. SCCR ratings vary by variant, for example up to 5 kA at 460 VAC on certain configurations and up to 100 kA SCCR on others, depending on the specific coil and version. The open construction means it is designed for panel mounting and may require an enclosure or protective housing as required by the application. Common applications include starting and protecting small, three‑phase motors in conveyors, pumps, and fans within industrial equipment, with compatibility to Square D accessories for mounting, wiring, and overload coordination. This model provides a compact, single‑device solution that combines motor starting and overload protection for light to moderate horsepower motor control in industrial environments.
