The Schneider Electric Altistart 22 Soft Starter — ATS22C14Q is an industrial soft starter designed for smooth start‑up and stopping of three‑phase asynchronous (induction) motors. It limits inrush current and reduces mechanical stress during motor starts, minimizing electrical disturbances, extending motor and equipment life, and improving reliability. The starter includes an integrated bypass contactor to decrease heat dissipation once the motor reaches full speed. It is suitable for pumps, fans, compressors, material handling equipment, and other industrial machinery. The slim design allows flexible installation in control panels or machine frames. SoMove software compatibility enables easy configuration and parameter transfer
