The ABB PSTX72-600-70 is a medium-voltage, medium-current soft starter from ABB's advanced PSTX series. Engineered for reliable and controlled acceleration and deceleration of three-phase induction motors, it effectively reduces mechanical stress on driven equipment (such as couplings and gearboxes) and minimizes electrical disturbances on the power supply network during motor startup. This unit is designed for heavy-duty industrial applications requiring robust performance.
