The 3RV20211KA10 belongs to the Siemens SIRIUS 3RV2 S0 series (family prefix 3RV2021). The "K" in the MPN denotes the 9–12.5A adjustable current band.
Family & Adjacent Ratings
The S0 frame accommodates motor loads from 1.1A up to 12.5A. Adjacent current bands in the same series include 3RV20211JA10 (7–10A), 3RV20211HA10 (5.5–8A), and 3RV20211FA10 (3.5–5A). Screw-type terminals are standard for this bulk-pack variant; spring-clamp versions (suffix "20") are available in the same current band.

3RV20211KA15 shares the 12.5A rating, 3-pole count, and DIN rail mounting. It adds a built-in auxiliary contact (1NO/1NC) and includes CE and VDE markings alongside the seed's approvals.
3RV20211KA20 matches on the core electrical specs but uses spring-clamp terminals instead of screw-type, and lists CE and VDE where the seed lists only ATEX/CCC/CSA/EAC/UL.
3RV20211FA10 uses the same screw-terminal bulk format and shares the rotary actuator, DIN rail mount, and 3-pole configuration, but targets a lower current band (3.5–5A).
