The Siemens 3RK1322-0JS02-1AA0 is an AS-interface compact reversing starter from the SIRIUS family, designed as a fully enclosed IP65-rated motor starting solution for distributed automation. The setting range covers 0.7 to 1 A, delivering 0.25 kW at AC-3 duty on a 400 V supply — sized for small reversing motor loads like conveyor drives or actuator valves in washdown zones.
AS-interface protocol onboard means this starter communicates directly on the AS-i bus without an external gateway — the two integrated inputs can capture local sensors or pushbuttons and pass status back to the controller.
Dimensions of 270 mm high, 120 mm wide, and 190 mm deep — this is a compact standalone enclosure, not a DIN-rail module, so it mounts via its own fixing points directly to a subplate or machine frame. Tab terminals on the main circuit mean the power wiring uses fast-on connectors — common in pre-wired harnesses for conveyor sections or packaging machinery where quick replacement matters. The 9-pole motor outgoing feeder and 9-pole power connection handle the reversing contactor wiring plus the AS-i bus and sensor inputs through a single cable entry — keeps gland-plate clutter down.
