The ATS22C41S6U belongs to Schneider Electric’s Altistart 22 series, engineered for controlled starting and stopping of high-power three-phase induction motors. It uses voltage ramp technology combined with torque control to reduce inrush current and minimize mechanical stress during motor startup.
This model integrates SCR-based power control with an internal bypass system, ensuring efficient thermal management and stable long-term performance. It has been widely used in industrial infrastructure, process plants, and heavy-duty manufacturing systems where uptime and equipment protection are critical.
However, this reference has now reached its end-of-commercialization stage, and Schneider Electric positions newer ATS430-series devices as its direct replacement for future projects.
ATS22C41S6 – Closely related S6 variant widely used in legacy systems
ATS22C32S6 – Common in heavy-duty pumping and conveyor systems
ATS430C41S6 – Modern replacement for upgraded automation projects
