ABB PSTX170-600-70 Soft Starter For Three Phase Induction Motors

ABB PSTX170-600-70 Soft Starter is a standalone soft-start device for three-phase induction motors, designed to deliver controlled ramping and smoother startup for mains supplies up to 600 V AC. It accepts a main voltage up to 600 V and uses a 100–250 V AC control input (50/60 Hz) to initiate start/stop sequences, helping to reduce inrush current and mechanical stress on driven equipment. The unit is rated for a nominal operational current around 171 A (commonly listed as 170 A) and is part of ABB's PSTX family, offering a compact, DIN-rail friendly solution for integrating soft-start functionality into electrical panels and drive systems.
