Siemens 3RV2321 Series S0 Circuit Breakers
3RV23214DC10 Family Context
The 3RV23214DC10 belongs to Siemens' S0 frame thermal-magnetic breakers in the 3RV2321 family, all sharing rotary actuators and DIN Rail mounting. The seed variant is classified as a thermal breaker type rather than magnetic, and ships in bulk packaging.
Specification Comparison
Readers must independently verify all specifications against manufacturer datasheets before procurement.

Why These Are Similar
- 3RV23214DC20: Same 25A rating, 3-pole, DIN Rail; shares the S0 frame and rotary actuator. Differs in breaker type (magnetic vs thermal) and adds CE and VDE approvals to the seed's CCC/CSA/EAC/UL listing. Ships as box quantity versus bulk.
- 3RV23214FC10: Same brand, S0 frame, 3-pole DIN Rail orientation. Rated at 40A—higher current capacity than the seed. Includes CE and VDE; ships in box packaging.
- 3RV23214CC10: Same structural parameters (3-pole, rotary, DIN Rail). Rated 22A—slightly lower than the seed. Magnetic breaker type; ships as box quantity.
Technical Notes
- Thermal and magnetic breaker types offer different trip characteristics; thermal provides inverse-time overload protection, magnetic provides instantaneous short-circuit tripping.
- Approval packages vary across the family range; confirm target market certifications match your installation geography.
- Bulk packaging on the seed may affect unit quantity procurement versus box-packaged alternates.
