Production Status and Panel-Build Quantities
The 3RV20211FA10 holds an Active product status in the SIRIUS 3RV2 series, confirming it remains in ongoing manufacturing with no end-of-life flag in current evidence. For OEM procurement teams committing to 10–100 unit panel builds, this eliminates the risk of selecting a breaker in EOL transition that could stall a production schedule.

Electrical Rating and Motor Feeder Fit
The 3RV20211FA10 provides a 3-pole, 5A, 690 V AC rating covering standard industrial distribution voltages. The thermal setpoint is adjustable within a 3.5–5A window, allowing fine-tuning to matched motor nameplate current without component substitution. The rotary actuator enables local manual reset after a fault—a practical feature for panel builders where clearance space limits auxiliary contact options.
Pin-compatible mounting: 3-pole DIN-rail form factor aligns with standard motor feeder layouts upstream of contactor/overload blocks. Panel designers can verify physical fit against the S00 frame envelope in the datasheet before locking the MPN into a BOM.
Screw Terminal vs Spring Terminal Decision
The 3RV20211FA10 uses screw terminals—a deliberate trade-off for panel builders prioritizing mechanical life and repeated torquing cycles over wiring speed. Screw termination supports larger conductor cross-sections and repeated rework cycles, which matters in panel builds where field termination may occur post-assembly.
Certifications for Hazardous-Area and Export
The approval suite includes ATEX, CCC, CSA, EAC, IECEx, and UL—covering EU hazardous-area motors, China CCC requirements, North American industrial panels, Eurasian Customs Union, and IECEx explosive atmospheres. ROHS3 Compliant status supports EU export compliance. The base 3RV20211FA10 does not list CE or VDE in its approval set; variants with integrated auxiliary contacts (3RV20211FA15, 3RV20211FA25) add CE and VDE to their certification strings.

Engineer's notes — electrical baseline
Treat the raw specification table as authoritative for siemens 3RV20211FA10 (MSP S0 3.5 - 5A SCREW); category path: Circuit Protection > Circuit Breakers; confirmed specs: series: 3RV2; Mounting Type: DIN Rail; Package: Bulk; Product Status: Active. Cross-check electrical limits, mounting style, output type, and lifecycle status against the target panel or machine design before freezing the BOM line or authorizing a field swap.
Field notes for cabinet wiring checks
Before energizing or replacing the module, align cabinet power rails, wiring plan, load type, terminal layout, and temperature class with both the manufacturer documentation and the as-built BOM.
Selection notes for footprint and electrical verification
Approve this line only when MPN, manufacturer, series, supply voltage, I/O style, mounting, and application role match the design intent. For alternates, diff the same fields first, then validate software/project hooks.
