It's an electromechanical DOL (direct-on-line) starter with bimetal overload protection, designed to mount directly on the machine frame or inside a junction box, not inside a central control panel. The IP65 enclosure means it handles washdown and dusty environments on the plant floor. Rated for 5.5 kW at 400 V AC-3, the motor-switching current setting range is 9…12 A via the bimetal relay. ## AS-Interface and connectivity This starter communicates over AS-Interface (AS-i protocol), not PROFIBUS DP. It includes bus communication capability and two integrated inputs for local sensors or pushbuttons. The main circuit connects via tab terminals — expect a 9-pole motor outgoing feeder and a 9-pole power connection, per the description. A motor brake output is built in, rated for 400 V AC, so you can control a mechanical brake directly from the starter without an external contactor. That's one less component to mount and wire. Dimensions are 270 mm high, 120 mm wide, 190 mm deep — a compact footprint for a 5.5 kW starter with integrated bus and brake control.","metaTitle":"Siemens 3RK1322-1KS02-0AA3 AS-i Compact Starter, 5.5 kW, IP6","metaDescription":"Siemens 3RK1322-1KS02-0AA3 AS-i compact direct starter. 5.5 kW at 400 V AC-3, setting range 9-12 A, IP65, with brake contact.
