It integrates an electromechanical DOL starter, bimetal overload protection, and bus communication into a single IP65 enclosure — no separate contactor, overload relay, or control cabinet needed at the point of use. Rated for 4 kW at AC-3 duty on 400 V three-phase, with a setting range of 7…10 A on the bimetal overload. ## Deployment context The 9-pole motor outgoing feeder and 9-pole power connection simplify wiring: one cable from the AS-i bus and 24 VDC supply, one cable to the motor, and the starter handles the rest. Two integrated inputs on the unit accept local sensors (e.g., position switches or emergency-stop buttons) without an extra I/O module. The built-in motor brake output (400 V AC) controls a holding brake directly, which is common for vertical-axis or palletizing applications where the load must not drift when power is removed.","metaTitle":"Siemens 3RK1322-1JS02-0AA3 AS-i Compact Starter, 7-10 A, 4 k","metaDescription":"Siemens 3RK1322-1JS02-0AA3 AS-i compact direct starter, 7-10 A setting range, 4 kW at AC-3 400 V, IP65, with brake contact and bus communication.
