That AC-3 rating means it's sized for standard three-phase squirrel-cage induction motors under starting conditions, not resistive heating loads. The IP65 enclosure lets it mount directly on the machine frame or conveyor section without an extra cabinet, so it's common on packaging lines, material handling spurs, and small pump stations where you want the starter close to the motor and the AS-i bus running the control. The bimetal motor protection element handles the thermal overload curve, and the integrated circuit-breaker-style short-circuit protection covers the magnetic trip. ## AS-i bus integration and I/O This starter communicates over AS-interface (AS-i) protocol, not PROFIBUS DP. That's the deciding factor for your control architecture: if your line uses AS-i flat cable and gateways, this part drops in directly; if you're on PROFIBUS, you need a different variant. The unit includes two integrated inputs for limit switches or sensors, plus a motor brake output rated 24 V DC / 3 A — useful for holding brakes on vertical-axis motors or conveyors that need to stop without coasting. Power and motor connections use tab terminals (9-pole motor outgoing feeder and 9-pole power connection), so the wiring is plug-and-play with the standard AS-i hybrid cable system. No screw terminals on the main circuit — the tab connectors are faster for panel builders but require the mating connector set. ## Environmental limits and approvals The equipment marking per DIN EN 61346-2 is 'Q', the standard identifier for switching devices in a plant schematic.","metaTitle":"Siemens 3RK1322-0CS02-0AA1 AS-i Compact Starter, 0.18-0.25 A","metaDescription":"Siemens SIRIUS 3RK1322-0CS02-0AA1 AS-interface compact direct starter.
