The electromechanical switching contact and bimetal motor protection make it a self-contained motor branch for reversing applications on a conveyor, gate, or actuator — no separate overload relay or contactor assembly needed inside a cabinet. ## AS-interface bus integration and motor brake output This starter communicates via AS-interface protocol, with bus communication enabled and two integrated inputs for local sensors or pushbuttons. The built-in motor brake output (product component Motor brake output = Yes) handles a 400 V AC brake coil directly, eliminating an external brake rectifier or contactor for motors with spring-applied brakes — a common requirement on vertical-axis or holding applications. The main current circuit connects via tab terminals, so it's wired with quick-connects rather than screw clamps, which speeds replacement on a live line. ## IP65 enclosure and ambient range","metaTitle":"Siemens 3RK1322-0FS02-1AA3 AS-i Reversing Starter, 0.12 kW,","metaDescription":"Siemens 3RK1322-0FS02-1AA3 AS-interface compact reversing starter. 0.12 kW AC-3 at 400 V, 0.35–0.5 A setting range, IP65, integrated brake contact, 50 kA breaking capacity.

The overall height is 270 mm. These dimensions fit a typical machine-mounted junction box or a small local control station, not a standard DIN-rail panel."},{"question":"Does this starter work with a motor that has a holding brake?","answer":"Yes, the starter includes a motor brake output rated for 400 V AC, so it can switch a spring-applied brake coil directly without an external brake contactor or rectifier."},{"question":"What is the short-circuit breaking capacity?","answer":"The maximum short-circuit breaking capacity (Icu) at 400 V is 50 000 A. This allows the starter to clear high-fault currents without requiring upstream fuses to blow, simplifying selective coordination."},{"question":"Can this replace a panel-mounted reversing contactor and overload?","answer":"In terms of function, yes — it combines reversing contactor, overload relay (bimetal), and short-circuit protection (circuit-breakers) in one IP65 package. But it is not a DIN-rail panel component; it is a self-contained enclosure meant for machine mounting. Panel wiring to tab terminals differs from screw-clamp contactor wiring."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RK1322-0FS02-1AA3","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RK1322-0FS02-1AA3 when reusing this data.
