The Schneider Electric Altistart 48 Soft Starter — ATS48C25Q is an industrial‑grade electronic soft starter designed to provide smooth starting and stopping of three‑phase asynchronous (induction) motors. This soft starter reduces mechanical and electrical stress by controlling the motor’s starting current and torque, improving reliability and extending equipment life. It is suitable for heavy‑duty industrial applications, including pumps, fans, compressors, conveyors, and general machinery. The unit supports torque control and integrates protections for phase loss, thermal conditions, and motor overload.
