Applications & Use Cases

The ABB PSTX370-600-70 soft starter is engineered for a wide range of industrial motor control scenarios where direct-on-line starting would cause excessive mechanical or electrical stress. Typical applications include pumps, fans, compressors, conveyors, and mixers. By controlling the ramp-up torque and reducing starting current, the PSTX370-600-70 extends motor and driven-equipment service life, lowers peak demand charges, and minimises voltage dip on the supply network. The unit suits installation in motor control centres (MCCs), standalone panels, and process automation systems across industries such as water treatment, HVAC, oil & gas, mining, and manufacturing.
