Schneider Electric ATS22D75Q is a three‑phase soft starter from the Altistart 22 series designed to provide smooth starting and stopping of three‑phase asynchronous motors in industrial applications. It reduces mechanical stress on the driven equipment and limits electrical inrush current by controlling the voltage and torque during motor start‑up. The integrated bypass minimizes heat generation and noise during running operation, and configuration can be managed via compatible software. The unit is suitable for applications such as pumps, fans, compressors, conveyors and other machinery requiring controlled motor acceleration.
