ABB PSR45-600-11 Softstarter (1SFA896111R1100)

The ABB PSR45-600-11 is a robust and compact softstarter designed to control three-phase induction motors up to 45 A. With an operational voltage range of 208–600 V AC and a 24 V AC/DC control supply, it provides efficient soft starting and stopping using a voltage ramp on two phases. This reduces mechanical wear and improves energy efficiency.

Built with a built-in bypass and dual relay outputs (RUN and TOR), it simplifies wiring while offering status LED indicators and optional Fieldbus communication. Ideal for compact panel designs and applications such as pumps, fans, and conveyors.
