The ATS22C48S6U 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 current limitation to reduce inrush current and mechanical stress during startup.
This model integrates SCR-based power control with an internal bypass system, ensuring efficient thermal management and stable long-term performance. It is widely used in heavy industrial environments such as infrastructure, process plants, and large manufacturing facilities where uptime is critical.
Although it remains a strong legacy solution, it has been phased out in favor of newer-generation Schneider soft starters for modern installations.
