It's an electromechanical DOL starter with bimetal motor protection, a setting range of 4.5 to 6.3 A, and a rated operating power of 2.2 kW at 400 V AC-3. That AC-3 duty rating means it's sized for starting squirrel-cage motors under load — pumps, fans, small conveyors — not just resistive heaters. The IP65 enclosure means it handles washdown and dust without a separate cabinet; you bolt it to the machine strut, run the motor cable and AS-i bus drop, and you're done. Communication is over AS-interface (AS-i) protocol, so it reports motor status and accepts start/stop commands over the same two-wire yellow cable that powers it. Two integrated inputs let you bring in limit switches or pushbuttons at the same node — no separate I/O block needed for local control. The main current circuit connects via tab terminals; the motor outgoing feeder is a 9-pole connector, so the whole unit swaps as a module, not a wiring project. ## Short-circuit rating and protection philosophy The maximum short-circuit breaking capacity at 400 V is 50 000 A (Icu). That's a serious SCCR for a 2.2 kW starter — it means this thing can sit on a high-fault bus without needing upstream fuses to knock the fault current down first. The short-circuit protection design uses circuit-breakers, not fuses, so coordination with a motor-protective breaker in the same SIRIUS family is straightforward. For a panel builder or site electrical engineer, that 50 kA number is the one that decides whether this starter can go into a given MCC bucket or machine junction box without a separate current-limiting device. ## Environmental fit and mounting reality IP65 and an ambient operating range of -25 to +55 °C — this is a washdown-rated, outdoor-capable unit. Out here in the grease, that's what keeps a motor starter alive on a washdown conveyor or a grain leg where the dust and moisture eat panel-mounted gear. The envelope is 270 mm high by 120 mm wide by 190 mm deep — big enough to house the contactor, bimetal relay, and AS-i electronics, but compact enough to mount on a machine frame without a separate enclosure. No DIN-rail mounting; it bolts directly to a backplate or machine strut via its own fixing points.","metaTitle":"Siemens 3RK1322-1GS02-0AA0 AS-i Compact Starter, 2.2 kW, IP6","metaDescription":"Siemens 3RK1322-1GS02-0AA0 AS-interface compact DOL starter. 2.2 kW at 400 V AC-3, setting range 4.5–6.3 A, IP65, 50 kA SCCR.
