Schneider Electric 8502SAO12S Motor Starter 3HP

Schneider Electric's Square D 8502SAO12S is a NEMA Type S, nonreversing motor starter (contactor) in Size 00 designed for three‑phase motors up to 3 HP. This 3‑pole device is intended to switch motor loads in control panels, with a typical current rating around 9 A at common high‑voltage values, and it is used with separate overload protection in the motor circuit. The exact coil voltage is model‑dependent within the SAO series; examples include 24 VAC coils (8502SAO12V01S) and 208 VAC coils (8502SAO12V08), illustrating the range of coil options available for this family. As part of the Type S lineup, the SAO variant includes auxiliary contact configurations to extend control capabilities, making it suitable for simple start/stop sequences in pumps, fans, conveyors, and other small industrial motors. Its Size 00 footprint keeps the unit compact for installation in slim panels and reduces space in motor control circuits.
