ABB S7HQ1200BWES8N Soft Starter For Three Phase Motors

ABB S7HQ1200BWES8N Soft Starter for Three Phase Motors is a high-current device designed to provide controlled starting for large three-phase motors. Rated for 1200 A at 600 V, it targets applications where soft-start capability is needed to limit inrush current and reduce mechanical stress during motor startup. As part of ABB’s S7HQ family, this unit applies a soft-start method to ramp motor voltage in three-phase systems, avoiding full line voltage at the moment of start. Typical uses include pumps, fans, and conveyors in industrial settings where startup transients can cause voltage sags or unwanted mechanical wear. When selecting this model, critical considerations include the motor current draw (up to 1200 A) and the available line voltage (600 V), as well as the requirement for operation on a three-phase supply. This ABB soft starter belongs to a lineage of robust, industrial-grade motor control solutions designed to improve starting performance and protect connected equipment in demanding environments.
