The ABB 1SFA896103R1100 is a PSR3-series soft starter with a voltage-ramp starting method — it gradually increases motor terminal voltage during start, reducing inrush current and mechanical stress on the driven load. Ramp time is adjustable from 0 to 20 seconds, letting you tune the acceleration profile to match pump, fan, or conveyor applications. Rated for 208 … 600 V AC three-phase supply, with a 24 V AC/DC control circuit — standard for panel integration where a 24 VDC PLC output drives the start command.
The initial voltage during start is adjustable between 40 % and 70 % of line voltage; the step-down ramp then finishes from 100 % down to 60 %. This two-stage profile lets you handle high-friction starts (higher initial kick) or gentle fluid coupling (lower kick). No built-in electronic overload — ABB recommends the MS116 manual motor starter (0.63 … 4.00 A range) for that function. If your BOM already uses MS116 breakers, this keeps the panel consistent. A run signal relay is present (green LED indication), but there is no fault signal relay, no bypass signal relay, and no overload signal relay — so if you need separate fault or bypass feedback to the PLC, plan for external auxiliary contacts. Screw terminals on main and control circuits, tightening torque 1 N·m (8.9 in·lb for UL/CSA). Main circuit accepts 0.75 … 2.5 mm² rigid wire; control circuit accepts 1 x 0.75 … 2.5 mm².
