What it is and where it lands
The Siemens 3RK1322-0GS02-0AA1 is a SIRIUS AS-interface compact direct starter — an electromechanical DOL starter in an IP65 enclosure rated for washdown environments. It is built for distributed motor control right at the machine, not inside a central panel, so it cuts wiring and cabinet space on conveyor, packaging, and material-handling lines. The setting range is 0.45 to 0.63 A, with a motor rating of 0.18 kW at AC-3 duty on a 400 V supply. That 0.18 kW figure is the maximum and minimum — this starter is sized for a specific small motor load, not a range of frame sizes. Protection is via bimetal overload relay, and short-circuit protection is handled by circuit-breakers. The unit includes a motor brake output rated 24 V DC / 3 A, a 9-pole motor outgoing feeder, and a 9-pole power connection with two integrated inputs.
Key ratings and what they mean for fit
The 50 kA short-circuit breaking capacity (Icu) at 400 V means this starter can safely interrupt fault currents up to that level without upstream devices needing to trip — important for selectivity in a line where multiple starters share a feeder. AS-interface protocol is built in, with bus communication active. No PROFIBUS DP option here — this is an AS-i node, so it drops onto a two-wire AS-i cable for both power and data, simplifying field wiring. The operating temperature range of -25 to +55 °C covers most factory-floor conditions without derating. Tab terminals on the main current circuit mean the motor leads terminate with quick-connect tabs, not screw clamps — verify your motor cable ends match before wiring.
Lifecycle and sourcing reality
Sourcing is straightforward: quoted to order against an RFQ. No official successor exists because none is needed — the part is still a standard catalog item in the SIRIUS compact starter family.
