Schneider Electric 8536SCO3S Three Phase Motor Starter

Schneider Electric’s Square D 8536SCO3S is a three‑pole NEMA Type S combination motor starter (Size 1) that integrates a magnetic starter with an overload protection relay based on melting alloy heaters, designed for reliable full‑voltage starting and stopping of AC motors. This 8536SCO3S assembly provides overload protection via a melting‑alloy thermal relay and is compatible with AC coil control, with coil voltage options documented across variants (examples include 24 V and 120 V AC). It carries a 27 A full‑load current rating and supports motor outputs such as 7.5 HP at 230 VAC or 10 HP at 460 VAC, making it suitable for compact, rugged motor control in industrial panels. As a combination starter, it consolidates power contacts and thermal protection in one enclosure, simplifying wiring and providing immediate motor protection for 3‑phase applications like pumps, conveyors, fans, and other machinery.
