Industrial SR22-30 Soft Starter Three-Phase Motor Controller

The Stellar SR22-30 is a compact, 30 A soft starter that reduces voltage during the start of a 3‑phase induction motor. It accepts 110–240 V on a single‑phase supply or 208–460 V on a three‑phase supply and is rated for up to 10 starts per hour. The unit is internally bypassed and built in a 55 mm frame for easy integration into control panels. Three front‑panel potentiometers let you tailor the starting sequence: Start Time, Starting Voltage, and Stop Time for a controlled ramp and deceleration. The SR22‑30 is designed to control two motor phases to limit inrush while delivering smoother acceleration. It includes internal overcurrent protection that activates when motor current exceeds about 110% of the starter’s rating, helping protect both the drive and the motor. This model is part of the Stellar SR22 series, a compact reduced‑voltage starter commonly used to minimize voltage fluctuations and mechanical stress during motor startup in light‑duty applications.
