The bimetal overload relay is set for 3.5 to 5 A, matching the motor full-load current in that power band. ## Integration details for panel and machine builders The main current circuit connects via tab terminals (9-pole motor outgoing feeder and 9-pole power connection), so the wiring pattern is fixed: match the mating connector to the tab layout. The unit includes a motor brake output rated 24 V DC / 3 A, which handles a small holding brake on the motor shaft — common for vertical-load reversing applications where the load must not drift when power is removed.","metaTitle":"Siemens 3RK1322-1FS02-1AA1 AS-i Reversing Starter, 1.9 kW","metaDescription":"Siemens SIRIUS 3RK1322-1FS02-1AA1 AS-interface compact reversing starter, IP65, bimetal protection, 3.5-5 A, 1.9 kW at 400 V AC-3, 50 kA SCCR.
