It integrates a bimetal motor protection relay, electromechanical switching contacts, and a motor brake output, all in one field-mounted package that communicates over AS-interface. The IP65 rating means the enclosure and connectors withstand washdown — this starter is designed for direct mounting on conveyors, packaging machines, or material handling sections where running control wiring back to a panel is impractical. The reversing contactor pair handles forward/reverse motor control, and the integrated brake output handles the holding brake on vertical-axis drives. The AC-3 rating of 0.9 kW at 400 V defines the maximum induction motor load this starter can switch under full-load starting conditions — that covers small conveyors, agitators, and fan drives up to that power. The bimetal overload relay is set via the 1.8 to 2.5 A range, matching the motor FLA. The electromechanical contactor design gives you visual confirmation of state and no leakage current in the off state — unlike a solid-state alternative, this part is a direct replacement for traditional reversing starters, just packaged for distributed mounting. The enclosure measures 270 mm high by 120 mm wide by 190 mm deep — sized for direct machine mounting via the integrated flanges. Main circuit connections use tab terminals; the AS-i bus connection and the two integrated inputs handle the control and feedback wiring. The 9-pole motor outgoing feeder and 9-pole power connection mean you land the motor cable and supply cable directly on the unit, not through a separate junction box. The AS-interface protocol onboard eliminates a separate bus coupler — the starter appears as a single node on the AS-i network, and the two integrated inputs can read limit switches or sensors directly.","metaTitle":"Siemens 3RK1322-1CS02-1AA3 AS-i Reversing Starter, 0.9 kW, I","metaDescription":"Siemens 3RK1322-1CS02-1AA3 AS-i compact reversing starter, 1.8-2.5 A, 0.9 kW at 400 V AC-3, IP65, with integrated brake contact and 50 kA SCCR.

That is a high interrupting rating for a compact reversing starter — it means the unit can clear a fault up to that level without needing upstream protection to operate, which simplifies panel coordination and allows installation on high-fault-capacity systems."},{"question":"Does this starter include a brake output?","answer":"Yes, the product component list includes a motor brake output. That is the additional contact set for controlling a DC or AC holding brake on vertical-axis motors — common on hoists, elevators, or vertical conveyors."},{"question":"What is the motor protection type?","answer":"The motor protection uses a bimetal overload relay, adjustable across the 1.8 to 2.5 A setting range. Bimetal relays provide thermal-model protection that tracks motor heating and cooling — they are the standard choice for reversing starters in this power class."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RK1322-1CS02-1AA3","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/3RK1322-1CS02-1AA3 when reusing this data.
