ABB PSR25-600-70 Softstarter (1SFA896108R7000)

The ABB PSR25-600-70 is a high-performance compact softstarter designed for three-phase motors up to 25 A. Ideal for pumps, compressors, conveyors, and HVAC systems, it enables smooth motor starting and stopping using two-phase voltage ramping, minimizing mechanical stress and extending system life.

With an integrated bypass contactor, both RUN and TOR relay outputs, and optional fieldbus compatibility, the PSR25-600-70 is a versatile solution for space-constrained panels. The unit also features intuitive front-mounted potentiometers for ramp time and start voltage adjustments.
