The ATS22C48Q belongs to Schneider Electric’s Altistart 22 series, engineered for controlled starting and stopping of very high-power three-phase induction motors. It uses voltage ramp technology combined with torque control to limit inrush current and reduce mechanical stress during startup.
This model is built for demanding industrial environments where large inertia loads and continuous operation are common. By combining SCR-based control with an integrated bypass system, it delivers efficient thermal management and reliable long-term performance. Although widely used in legacy installations, it has now been phased out in favor of newer Altivar Soft Starter platforms.
