It switches a 0.25 kW motor at AC-3 duty on 400 V, with a bimetal overload relay adjustable from 0.7 A to 1 A. The IP65 housing means this unit mounts directly on the machine frame or conveyor section, not inside a control cabinet — it survives washdown and dust exposure on the plant floor. The 0.25 kW rating at AC-3 400 V tells you this starter is sized for small three-phase induction motors — fractional-horsepower pumps, small conveyors, or valve actuators. The setting range of 0.7...1 A matches the full-load current of a motor in that power band; you set the bimetal relay to the motor nameplate FLA. The integrated motor brake output is a practical feature for reversing applications where the load must stop quickly before reversing direction — think indexing conveyors or turntables. The electromechanical switching contact gives you positive air-gap isolation, which matters for safety-related stop circuits where solid-state leakage is unacceptable. ## Deployment context This is a distributed motor starter for AS-i networks. It communicates over the AS-interface protocol, not PROFIBUS DP, so it belongs on an AS-i flat-cable segment with a gateway back to a higher-level controller. The IP65 enclosure allows mounting directly on the machine frame, saving cabinet space and reducing wiring runs. The 9-pole motor outgoing feeder and 9-pole power connection are tab terminals — plan for fast-on connectors rather than screw clamps. Ambient range of -25 to +55 °C covers most production-floor conditions without derating.","metaTitle":"Siemens 3RK1322-0JS02-1AA3 AS-i Compact Reversing Starter, 0","metaDescription":"Siemens SIRIUS 3RK1322-0JS02-1AA3 AS-i compact reversing starter, 0.7-1 A setting range, 0.25 kW at AC-3 400 V, IP65.
