The Siemens 3RK1322-1KS02-1AA4 is an AS-Interface compact reversing starter in an IP65 enclosure. It is a reversing starter with electromechanical switching and bimetal motor protection.
Where it goes — deployment context
IP65 means the enclosure is dust-tight and protected against low-pressure water jets — this starter mounts directly on the machine frame or conveyor structure, not inside a control cabinet. It communicates over AS-Interface for start/reverse commands and status feedback, with two integrated inputs for local pushbuttons or sensors. The motor brake output handles a DC brake coil up to 500 V DC / 1 A, so it suits vertical-axis or high-inertia loads that need a holding brake.
