It handles a motor load up to 1.1 kW at 400 V under AC-3 duty (the standard for squirrel-cage induction motors), with a setting range of 2.2 to 3.2 A on the bimetal overload relay. The electromechanical switching contacts reverse the motor direction via the AS-i bus, and the integrated brake output handles the holding brake on vertical-axis or high-inertia loads. The 1.1 kW AC-3 rating at 400 V is the headline number — it tells you this starter is sized for a 1.1 kW motor drawing roughly 2.6 A at full load. The bimetal overload covers 2.2 to 3.2 A, so you set it to the motor nameplate FLA. ## Bus integration and wiring This starter communicates over AS-Interface (AS-i), not PROFIBUS DP — so it plugs directly into an AS-i yellow flat cable loop from the master. The main circuit connects via tab terminals (9-pole motor outgoing and 9-pole power connection), which are standard for this form factor. Two integrated digital inputs on the unit let you wire local sensors (e.g., limit switches or emergency-stop buttons) directly into the AS-i node, saving a separate I/O block.","metaTitle":"Siemens 3RK1322-1DS02-1AA3 AS-i Reversing Starter, 1.1 kW AC","metaDescription":"Siemens 3RK1322-1DS02-1AA3 AS-Interface compact reversing starter, IP65, 2.2-3.2 A setting range, 1.1 kW at 400 V AC-3, with integrated brake contact and 2 inputs.
