The setting range of 2.8 to 4 A means it's sized for small motors — pumps, fans, small conveyors — where you want the motor protection and switching integrated into one field-mounted package. IP65 means the enclosure and all connections withstand direct hose-down and dust ingress — this starter mounts directly on the machine frame in washdown zones, not inside a panel. The headline rating is the AC-3 motor switching capacity: 1.5 kW at 400 V. That's the real-world number for sizing — it's the maximum induction motor load this starter can switch under full-load running conditions. Don't oversize it: the 2.8 to 4 A bimetal setting range is the motor FLA window, and the part is optimized for that band. If your motor draws 2.5 A or 4.5 A full-load, this isn't the right setting range. For selectivity, verify that the upstream protective device's let-through energy stays within the starter's withstand rating. AS-interface protocol onboard means this starter communicates directly on the AS-i bus network — no gateway module needed for basic I/O. It carries two integrated inputs, so you can wire limit switches or pushbuttons directly into the starter without a separate I/O block. No PROFIBUS DP on this variant, so if your plant backbone is PROFIBUS, you'll need an AS-i gateway to bridge the networks. Physical footprint: 120 mm wide, 190 mm deep, 270 mm tall. The main circuit connects via tab terminals — expect blade-type quick-connects, not screw clamps. The motor outgoing feeder and power connection are both 9-pole, so plan your cable assembly for a 9-pin circular or rectangular connector at the machine interface. No motor brake output on this variant — if your application needs a holding brake, you'll need a different order code. Mounts directly to the machine frame or a mounting plate via the IP65 enclosure's fixing points. No DIN rail — this is a field-mounted device. The -25 to +55 °C operating range and IP65 rating mean it's ready for washdown environments, but keep the cable glands oriented downward to prevent water pooling at the entry point.","metaTitle":"Siemens 3RK1322-1ES02-0AA0 AS-i Compact Starter, 2.8-4 A, IP","metaDescription":"Siemens AS-i compact direct starter, IP65, setting range 2.8-4 A, AC-3 1.5 kW/400 V, 50 kA SCCR, AS-interface bus communication.
