It's designed for the AS-interface bus network, with two integrated inputs for local sensors and a 9-pole power connection via tab terminals. Rated for 2.2 kW at AC-3 duty on a 400 V supply, the setting range covers 2 A to 5.95 A — so it handles standard 0.75 kW to 2.2 kW three-phase motors. The solid-state motor protection eliminates nuisance thermal overload trips common with bimetal relays in high-cycle applications. The IP65 rating means the entire starter — electronics, power connections, and bus interface — withstands washdown and dust ingress. Mount it directly on the machine frame or conveyor structure, not back in the panel. That saves cabinet space and shortens motor power cabling. ## Breaking Capacity and Short-Circuit Coordination The 100 kA short-circuit breaking capacity (Icu) at 400 V is the standout spec for anyone doing selectivity studies. For a distributed starter mounted at the motor, this means you can size the upstream feeder breaker for the cable rating, not the fault current — the starter handles the full 100 kA itself. Short-circuit protection is fuse-based (design of short-circuit protection: fuse). The solid-state switching contacts don't weld like conventional contactors, so the fuse is the only sacrificial element in a fault event. That keeps replacement costs low — swap the fuse, not the starter. ## AS-Interface Integration and I/O This starter communicates via AS-interface protocol — not PROFIBUS DP. That's a key distinction: AS-i is a bit-level fieldbus for simple sensors and actuators, running on a two-wire flat cable that also carries 24 V DC power. The starter's two integrated inputs let you wire local limit switches or proximity sensors directly into the unit, reducing junction box complexity. The DC voltage type (24 V nominal from the AS-i bus) powers the electronics and the solid-state switching. No separate control voltage needed — the bus cable is the power source. The equipment marking per DIN EN 61346-2 is Q, confirming it's classified as a motor starter in the schematic. Dimensions: 190 mm deep, 120 mm wide, 270 mm tall. That's a compact footprint for a fully self-contained starter with bus interface and integrated inputs. No brake output on this variant (product component motor brake output: No), so if you need a motor brake, this isn't the version — look for the -0BS12-0AA0 suffix with brake contact.","metaTitle":"Siemens 3RK1322-0BS12-0AA0 AS-i Compact Starter, 2.2 kW, IP6","metaDescription":"Siemens SIRIUS AS-i compact starter IP65, DOL solid-state motor starter, setting range 2-5.95 A, 2.2 kW AC-3 at 400 V, 100 kA breaking capacity.
