The Schneider Electric ATS01N222QN is a 22 kW (30 HP), 3-phase soft starter from the Altistart 01 series. Designed for standard squirrel-cage motors, it provides controlled acceleration and deceleration to reduce mechanical stress and inrush current. The "QN" suffix typically indicates a specific control voltage version (e.g., 110-120V AC). It is a compact, cost-effective solution for pump, fan, and conveyor applications.
