It's an electromechanical reversing starter with bimetal motor protection and circuit-breaker-based short-circuit protection, designed for distributed motor control on a machine frame or conveyor line where you need forward/reverse without a separate panel. The unit communicates over AS-Interface (AS-i), so it drops onto a two-wire bus cable for both power and data. No PROFIBUS DP on this variant — the onboard bus communication is strictly AS-i. That simplifies wiring: one flat cable carries the 24 VDC supply and the control signals to the starter, and the reversing contactor set handles the motor switching locally. The motor rating is 0.12 kW at AC-3 duty on a 400 V supply. AC-3 is the standard category for squirrel-cage induction motors — starting, stopping, and reversing under load. That 0.12 kW figure governs the real-world motor size you can switch; it's not the contactor's thermal current but the motor power the bimetal overload can protect. The setting range of 0.35 A to 0.5 A matches small motors in that power band — think a fractional-horsepower conveyor drive or a small agitator. The short-circuit breaking capacity is 50,000 A at 400 V. That's a high interrupting rating for a compact starter — it means the unit can clear a fault on a high-capacity supply transformer without upstream fuses needing to coordinate. The IP65 seal keeps moisture and dust out across that range. ## Physical integration and wiring Dimensions are 190 mm deep, 120 mm wide, 270 mm tall. The width is the key panel-space number — at 120 mm, it's wider than a typical contactor but the enclosure integrates the overload relay, reversing contactors, AS-i interface, and the circuit-breaker short-circuit protection into one package. Main circuit connections are tab terminals, which are common for quick-connect wiring in distributed installations. The unit includes a 9-pole motor outgoing feeder and a 9-pole power connection, plus two integrated inputs for local sensors or pushbuttons.","metaTitle":"Siemens 3RK1322-0FS02-1AA0 AS-i Reversing Starter, 0.35-0.5","metaDescription":"Siemens 3RK1322-0FS02-1AA0 AS-Interface compact reversing starter.
