The Siemens 3RK1322-0BS02-0AA0 is a direct starter in an IP65-rated enclosure, designed for switching and protecting small motor loads — think conveyors, pumps, or fans in washdown or outdoor zones where the enclosure itself handles the ingress protection.
Panel and deployment context
This is not a DIN-rail component — it's a standalone enclosure (190 x 120 x 270 mm) that mounts directly on the machine frame or a sub-panel. Power in and out goes through ISO 23570 sockets; the control supply and AS-i communication land via the AS-i shaped cable with cutting/clamping method, which means no separate terminal blocks for the bus connection. The two M12 digital inputs are pre-wired for local sensors or limit switches. If you're replacing a panel-mounted contactor with a distributed starter, this part eliminates the control cabinet entirely for that motor branch.
