The Siemens 3RK1322-1GS02-1AA0 is a SIRIUS AS-Interface compact reversing starter — an electromechanical motor starter with a bimetal overload relay, built into an IP65 enclosure for direct machine-mount or washdown-area installation. The setting range of 4.5 to 6.3 A lets it cover a tight band of motor FLA without swapping heater packs.
Communication is via AS-Interface protocol (no PROFIBUS DP on this variant), with two integrated inputs for local sensors or pushbuttons, and the bus communication function is built in — no separate gateway module needed.
The enclosure measures 270 mm high, 120 mm wide, and 190 mm deep. The 9-pole motor outgoing feeder and 9-pole power connection match standard AS-i cabling schemes.
