Schneider Electric 9065ST320U Three Phase Soft Starter

Schneider Electric's Square D 9065ST320U is a three‑phase solid‑state overload relay (NEMA Size 3) for protective motor control, rated 30 to 90 A on up to 600 V AC, and designed to mount on compatible Square D motor starters to guard three‑phase motors from thermal overload. As part of the 9065 family, the device provides solid‑state, fast overload protection across three poles. Schneider Electric notes compatibility with traditional Square D starters, including mounting on the 8536 S family, for integrated motor protection. Distributor listings confirm the 9065ST320U specification as a 3‑pole device with a 30–90 A range at 600 VAC, available from DigiKey, Mouser, and Grainger.
