ABB PSTX142-600-70 Soft Starter Three Phase Motors

ABB PSTX142-600-70 Soft Starter is a three-phase motor soft-start device that reduces inrush current and smooths acceleration and deceleration to protect electrical and mechanical components. It is rated for about 142 A (commonly listed as 143 A in retailer listings) and supports supply voltages up to 600 V AC, with a typical operating range of 208–600 V in three-phase systems. As part of ABB’s PSTX soft starter family, this model provides controlled motor starting for standard-duty applications, helping mitigate voltage dips and torque shocks in equipment like pumps, fans, and conveyors. The PSTX142-600-70 is selected when a 142 A, 208–600 V soft-start solution is required for a three-phase motor, aligning with ABB’s 600 V PSTX offerings and enabling reliable, straightforward commissioning for industrial environments.
