It integrates an electromechanical reversing contactor, a bimetal overload relay set for 0.28 to 0.4 A, and short-circuit protection via circuit-breakers, all in one 120 x 270 x 190 mm package. The IP65 rating means the entire starter — contacts, overload, and AS-i bus interface — is sealed against dust and low-pressure water jets, so it mounts directly on the machine frame in washdown or outdoor environments. No need for a separate enclosure. ## AS-Interface Integration and Brake Output Communication is over AS-interface (AS-i) protocol — no PROFIBUS DP on this variant. The starter includes bus communication capability and two integrated digital inputs for local sensors or limit switches, reducing the need for separate I/O blocks at the machine. A motor brake output is built in, rated for 500 V DC / 1 A, so it can directly control a DC brake coil on the motor without an external relay. The main circuit connects via tab terminals — quick-connect blades rather than screw clamps — which speeds wiring in high-volume machine builds. The equipment marking per DIN EN 61346-2 is Q, the standard identifier for motor starters in schematic diagrams.","metaTitle":"Siemens 3RK1322-0ES02-1AA4 AS-i Reversing Starter, 0.1 kW, I","metaDescription":"Siemens 3RK1322-0ES02-1AA4 AS-interface reversing starter, 0.28-0.4 A setting range, 0.1 kW at 400 V AC-3, IP65.
