It's an electromechanical DOL starter with bimetal motor protection and integrated short-circuit protection via circuit-breakers, so it handles both overload and fault current in one package. Communication is over AS-Interface (AS-i) protocol, not PROFIBUS DP, so this unit plugs directly into an AS-i yellow cable loop. It carries two integrated inputs for local sensors (e.g., limit switches or emergency-stop buttons) and a motor brake output rated at 500 V DC / 1 A — useful for holding brakes on vertical-axis motors. The 9-pole motor outgoing feeder and 9-pole power connection mean the wiring harness is pre-configured; you terminate the AS-i flat cable and the motor cable, not individual control wires. For a distributed starter mounted on a machine frame rather than inside a switchgear panel, that SCCR headroom is the difference between a coordinated trip and a blown-open housing. Dimensions are 120 mm wide × 270 mm high × 190 mm deep. The IP65 housing is designed for direct machine-mounting — bolt it to the frame or a mounting plate, run the AS-i flat cable and motor cable, and you're done. No DIN rail, no separate contactor/enclosure assembly. The equipment marking per DIN EN 61346-2 is 'Q', the standard identifier for motor-starter equipment in schematic diagrams.","metaTitle":"Siemens 3RK1322-1CS02-0AA4 AS-i Compact Starter, 1.8-2.5 A,","metaDescription":"Siemens 3RK1322-1CS02-0AA4 AS-Interface compact starter, direct-on-line, 1.8-2.5 A setting range, 0.9 kW at AC-3/400 V, IP65, with motor brake output.
