It combines a reversing contactor, bimetal overload protection, short-circuit protection via circuit-breakers, and bus communication into a single IP65 enclosure — meaning it mounts directly on the machine frame or conveyor section, not inside a central control panel. Rated for 0.37 kW at 400 V AC-3 duty, the starter's adjustable overload range covers 0.9 to 1.25 A, making it a fit for small reversing motor loads such as shuttle gates, diverters, or indexing tables. The electromechanical switching contact handles the reversing logic internally, so the AS-i network only sends direction and start/stop commands. A built-in motor brake output (24 V DC / 3 A) is included for holding-brake applications, and the unit provides two integrated inputs for local sensors or pushbuttons — typical for a stand-alone reversing station where you want local control plus network visibility. The 0.37 kW AC-3 rating at 400 V is the motor switching capacity under the most common induction-motor starting condition (AC-3: starting and switching off running motors). This is not a resistive-heating rating — it governs the inrush and breaking of motor current. The AS-Interface protocol connection (yes, not PROFIBUS DP) is the communication backbone here. The starter acts as an AS-i slave, receiving direction and start/stop telegrams and reporting back status and overload trips. Two integrated inputs allow connection of limit switches or emergency-stop buttons directly to the unit, reducing field wiring. ## Panel and machine integration The 190 mm depth, 120 mm width, and 270 mm height define the envelope for machine-mounted installation. No DIN rail is needed — the IP65 housing is designed for direct machine or bracket mounting, with the AS-i cable daisy-chained through the integrated bus connection.","metaTitle":"Siemens 3RK1322-0KS02-1AA1 AS-i Compact Reversing Starter, 0","metaDescription":"Siemens SIRIUS 3RK1322-0KS02-1AA1 AS-Interface compact reversing starter, IP65, 0.9-1.25 A setting range, 0.37 kW at 400 V AC-3, with integrated brake output and two inputs.
