It's an electromechanical DOL (direct-on-line) starter with a setting range of 0.14 to 0.2 A, delivering up to 0.06 kW at AC-3 duty on a 400 V supply. The 0.14...0.2 A setting range paired with a bimetal overload relay means this starter is sized for fractional-horsepower motors — think small conveyors, vibratory feeders, or cooling fans. The AC-3 rating at 400 V (0.06 kW) confirms it handles starting currents typical of squirrel-cage induction motors without nuisance tripping. The 50 kA short-circuit breaking capacity (Icu) at 400 V is unusually high for a starter this size, giving selectivity headroom in a panel fed by a larger upstream breaker. That SCCR lets it sit downstream of a 50 kA-rated feeder without requiring a current-limiting fuse for the short-circuit coordination. The integrated motor brake output handles the brake coil directly, saving an external relay. Two integrated inputs bring sensor signals back to the AS-i bus without extra I/O modules. Communication is AS-interface protocol — not PROFIBUS DP — so this part belongs on an AS-i network, not a PROFIBUS drop. ## Deployment Context The 270 mm height, 120 mm width, and 190 mm depth mean it fits in a standard machine-mount footprint, not a DIN-rail panel.","metaTitle":"Siemens 3RK1322-0BS02-0AA3 AS-i Compact Starter, 0.14-0.2 A,","metaDescription":"Siemens SIRIUS 3RK1322-0BS02-0AA3 AS-interface compact direct starter.
