The ABB PSR16-600-70 softstarter (SKU 1SFA896107R7000) is a compact 3-pole, 16A electronic motor soft-starting device designed for smooth acceleration and deceleration of three-phase AC induction motors rated up to 7.5 kW. Operating across a wide supply voltage range of 208–600 V AC with a control voltage of 110–250 V, the PSR16-600-70 reduces mechanical stress, inrush current, and wear on driven machinery during start and stop cycles, making it ideal for conveyors, pumps, fans, and compressors in industrial automation environments.
The ABB PSR16-600-70 softstarter is well suited for a broad range of industrial and commercial motor-driven applications where controlled starting and stopping is essential. Typical deployments include centrifugal pumps, HVAC fans, belt conveyors, compressors, and agitators. By limiting peak inrush current during start-up, the PSR16-600-70 helps reduce demand charges, protects mechanical couplings, and extends the service life of motors and driven equipment. Its wide supply voltage range (208–600 V AC) and compact 45 mm DIN-rail footprint make it straightforward to integrate into existing control panels across global installations.
