It carries a setting range of 2.2 to 3.2 A and a maximum short-circuit breaking capacity (Icu) of 50 000 A at 400 V — meaning it can safely clear a bolted fault on a 400 V line without upstream coordination cascading open. Built for IP65-rated environments, the housing withstands washdown and dust ingress directly on the machine frame — no separate control cabinet needed for the motor circuit. It communicates over AS-Interface protocol and includes two integrated inputs plus a motor brake output rated 24 V DC / 3 A for holding brake control on vertical-axis drives. Operating ambient temperature spans -25 to +55 °C, which covers most production-floor conditions including cold stores and non-air-conditioned lines in warm climates. The AC-3 duty rating (1.1 kW at 400 V) governs motor starting — the contactor portion is sized for the inrush current of a 3-phase induction motor up to that power, not just the running load. The setting range is 2.2 to 3.2 A on the bimetal overload relay. ## Integration notes for the controls integrator The main current circuit connects via tab terminals.","metaTitle":"Siemens 3RK1322-1DS02-1AA1 AS-i Reversing Starter, 1.1 kW, I","metaDescription":"Siemens 3RK1322-1DS02-1AA1 AS-Interface compact reversing starter.
