The Schneider Electric ATS48C79Q is a 79 A Soft Starter from the Altistart 48 series. Designed for three-phase asynchronous motors operating in the 230V to 415V AC voltage range, it provides smooth acceleration and deceleration to reduce mechanical stress and inrush current. The "C" indicates a Compact enclosure (IP20) for panel mounting, and the "Q" suffix typically denotes a control voltage of 110-120V AC. It features an integrated bypass contactor for energy-efficient running and comprehensive motor protection functions.
