The setting range of 2.8 to 4 A covers small conveyors, pumps, and indexing drives common on automotive assembly lines. Bimetal motor protection handles overloads thermally; the electromechanical contact design gives deterministic pick-up and drop-out timing, which matters when you're sequencing multiple axes against a takt clock. ## Integration and connectivity It communicates over AS-Interface (not PROFIBUS DP), so it drops into an AS-i network segment directly — no gateway required at the device level. The built-in motor brake output simplifies wiring for vertical-axis or fast-stop applications. At 190 mm deep, 120 mm wide, and 270 mm tall, it's sized for machine-side mounting rather than a crowded DIN-rail panel.","metaTitle":"Siemens 3RK1322-1ES02-0AA3 AS-i Compact Starter, 2.8-4 A, 1.","metaDescription":"Siemens 3RK1322-1ES02-0AA3 AS-Interface compact starter, electromechanical DOL, 2.8-4 A, 1.5 kW at 400 V AC-3, IP65, bimetal protection, brake contact, current production.
