The setting range of 2.2 to 3.2 A means the overload relay is factory-set for that window; you adjust the bimetal trip within it to match the motor full-load current. The IP65 protection class means the enclosure withstands hose-directed water and dust ingress — suitable for washdown zones in food processing, automotive assembly, or outdoor material handling where a central panel isn't practical. The electromechanical switching contact and bimetal motor protection are field-proven technology; no firmware to corrupt, no configuration to lose on power cycle. ## Fieldbus Integration and I/O This starter communicates via AS-interface protocol, not PROFIBUS DP. That makes it a node on a two-wire AS-i bus carrying both power and data — common in distributed I/O architectures where you want motor control and sensor feedback on the same cable. The two integrated inputs accept limit switches, proximity sensors, or emergency-stop contacts directly into the starter, reducing junction box wiring. The 9-pole motor outgoing feeder and 9-pole power connection handle the motor cable and control wiring through a single connector interface. ## Short-Circuit Coordination and Breaking Capacity The maximum short-circuit breaking capacity (Icu) is 50,000 A at 400 V — a high-fault rating that allows this starter to be installed on industrial networks with substantial available fault current without requiring upstream current-limiting fuses. The short-circuit protection design uses circuit-breakers, meaning the coordination between the upstream breaker and the starter's bimetal overload is defined; verify the manufacturer's coordination tables for your specific breaker model.","metaTitle":"Siemens 3RK1322-1DS02-0AA0 AS-i Compact Starter, 2.2–3.2 A,","metaDescription":"Siemens 3RK1322-1DS02-0AA0 AS-i compact direct starter, electromechanical DOL, setting range 2.2–3.2 A, AC-3 1.1 kW/400 V, IP65, with 2 integrated inputs.
