The ATS22C48S6 belongs to Schneider Electric’s Altistart 22 soft starter family, designed 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 motor startup.
This model integrates SCR-based power control with an internal bypass system, ensuring efficient thermal performance and stable long-term operation. It has been widely used in heavy industrial environments such as infrastructure systems, process plants, and large manufacturing facilities.
Although it remains a strong legacy solution, it has been officially discontinued and replaced by newer generation soft starters in Schneider Electric’s portfolio.
