The Schneider Electric Altistart 22 Soft Starter – ATS22C11Q is a three-phase electronic soft starter designed to provide smooth starting and stopping of asynchronous (induction) motors. It limits inrush current and reduces mechanical stress on motors and driven equipment during start-up, enhancing equipment longevity and reducing electrical disturbances. The unit features an integrated bypass to reduce heat dissipation and noise, and is suitable for applications such as pumps, fans, compressors, and material-handling machinery. Compatibility with Schneider’s SoMove configuration software allows easy set-up and parameter transfer.
