The Schneider Electric Altistart 48 Soft Starter — ATS48C32Q is a heavy‑duty industrial soft starter designed for smooth start and stop control of three‑phase asynchronous (induction) motors. It provides controlled torque during acceleration and deceleration to reduce mechanical stress and limit inrush current. This soft starter is suitable for demanding applications such as pumps, fans, compressors, conveyors, and other large industrial machines. It offers integrated motor and starter protection and complies with international soft starter safety and control standards.
