ABB PSTX142-69-70 Molded Case Circuit Breaker

ABB PSTX142-690-70 is a 3-phase softstarter from ABB’s PSTX family, designed to smoothly energize large motors by limiting inrush current with a line voltage range of 208 to 690 V AC at 50/60 Hz. The model is identified by part number 1SFA898210R7000 and uses a control supply in the 100–250 V AC range to govern the start/stop sequence. As a softstarter, it reduces peak starting torque and electrical stress on the drive system, enabling safer, more reliable operation of three-phase induction motors in industrial settings. Widely used in conveyors, pumps, and fans where controlled acceleration and energy efficiency matter, the PSTX142-690-70 supports high-voltage mains up to 690 V and integrates into ABB’s broader motor-control offerings for automation.
