ABB 1SFA896103R7000

The PSR3-600-70 softstarter boasts a maximum operational current of 3.9 A, with an operating voltage range spanning from 208 to 600 V AC. The control voltage is set between 100 and 240 V AC at 50/60 Hz.

PSR features a two-phase control soft start and stop via a voltage ramp, with built-in bypass for easy installation and energy efficiency. A RUN signal is available from a relay output in NO (normally open state). The start/stop ramp and time can be easily adjusted using three potentiometers on the front.

This softstarter is often used in combination with a manual motor starter (MMS) from ABB, and mechanical connection kits are available. Fieldbus communication is another popular option, enabled by an external adaptor and a Fieldbus plug.

PSR is part of our compact range of softstarters, offering basic functionality and values. They are suitable for small three-phase motors with nominal currents from 3 to 105 A and can handle up to 100 starts per hour. Common applications include pumps, fans, compressors, and conveyors.
