It is designed for direct-on-line reversing control of small three-phase motors up to 0.25 kW at 400 V AC-3, with a setting range of 0.7 to 1 A. The unit includes a motor brake output (24 V DC / 3 A) and two integrated inputs, making it a drop-in solution for distributed motor control in AS-i networks. The 0.7 to 1 A setting range on the bimetal overload matches the full-load current of a motor in that power band; set it to the motor nameplate FLA. The IP65 enclosure means the entire unit — contacts, overload, and bus electronics — withstands washdown and dust ingress, so it mounts directly on the machine frame or conveyor line without a separate panel. ## Integration and connectivity This starter communicates over AS-interface (AS-i protocol), not PROFIBUS DP — verify your network master supports AS-i. The main current circuit connects via tab terminals, typical for IP65 field-mount units; the 9-pole motor outgoing feeder and 9-pole power connection are pre-wired for quick hookup. The integrated brake output (24 V DC / 3 A) controls a motor holding brake directly, saving an external relay. Two integrated inputs accept limit switches or sensors.","metaTitle":"Siemens 3RK1322-0JS02-1AA1 AS-i Reversing Starter, 0.25 kW,","metaDescription":"Siemens SIRIUS AS-i compact reversing starter, 0.25 kW at 400 V AC-3, IP65, with bimetal overload and integrated brake contact.
