1SFA896104R1100

ABB 1SFA896104R1100 PSR6-600-11 Soft starter is a compact 6 A class three-phase soft starter from ABB’s PSR series, designed for smooth starting and stopping of small AC induction motors. It operates on a 208–600 V AC main circuit and uses a 24 V AC/DC control supply. ABB’s North American eCatalog lists 6.1 A normal-duty output current, while ABB India markets the unit as 6.8 A; the model designation itself is PSR6-600-11. The unit uses two-phase voltage-ramp control for soft start and soft stop, helping reduce mechanical shock, abrupt torque and starting stress compared with direct-on-line starting. It includes a built-in bypass, which improves efficiency and reduces heat generation once the motor reaches normal running speed. A RUN signal is available from a normally-open relay output, and the ramp settings are adjusted using three potentiometers on the front. Typical PSR applications include pumps, fans, compressors, conveyors and general small industrial motor-control systems.
