The ABB PSR85-600-70 softstarter (SKU: 1SFA896114R7000) is a 3-pole, 85 A compact softstarter rated for 208–600 V AC supply, delivering smooth motor starting and stopping for loads up to 45 kW. Designed for demanding industrial automation environments, the PSR85-600-70 reduces mechanical stress and inrush current, extending motor and drivetrain service life while fitting neatly into space-constrained control panels with its 70 mm × 220 mm × 180 mm profile.
The ABB PSR85-600-70 softstarter is widely used across industrial automation and motor control applications where controlled acceleration and deceleration are essential. Typical applications include pumps, fans, compressors, conveyors, and centrifugal loads in manufacturing plants, water treatment facilities, HVAC systems, and process industries. With its wide voltage range of 208–600 V AC and compact DIN-rail-compatible form factor, the PSR85-600-70 integrates seamlessly into control panels, motor control centres (MCCs), and enclosed switch assemblies. The 110–250 V control voltage range accommodates diverse plant control architectures without additional transformers.
