Siemens 3RV23111KC20 Circuit Breaker Selection Guide
Engineering Verification Checklist
- Confirm load nameplate FLA is ≤12.5A and motor service factor or time-duty rating is compatible with the magnetic-only trip curve
- Verify available short-circuit current at the breaker line terminals does not exceed the interrupting rating specified for this frame
- Validate short-circuit coordination with upstream protective device per NEC/ IEC coordination study requirements
- Confirm DIN Rail (EN 60715) profile dimension and mounting rail material are compatible with enclosure grounding provision
- Check that enclosure thermal derating (if any) does not push effective current derating below the connected load FLA
- Verify all field-wiring and load-side terminal torque values per Siemens S00 terminal specifications
- Confirm auxiliary contact or accessories (if specified) are listed for use with the 3RV2311x prefix series
