ABB PSR37-600-11 Softstarter (1SFA896110R1100)

The ABB PSR37-600-11 is a high-performance compact softstarter designed for three-phase motors with a rated current of up to 37 A. Operating across a wide voltage range of 208–600 V AC and powered by a 24 V AC/DC control voltage, this softstarter provides smooth acceleration and deceleration using a two-phase voltage ramp.

Equipped with a built-in bypass contactor, dual NO relay outputs (RUN and TOR), and front-panel potentiometer control, the PSR37-600-11 simplifies installation while increasing efficiency. It’s ideal for controlling pumps, compressors, fans, and conveyors, and supports up to 100 starts per hour with optional Fieldbus communication.
