Siemens 3RV24211DA10 Motor Starter Protector
The 3RV24211DA10 belongs to the Siemens SIRIUS 3RV2 family of motor starter protectors. The MPN prefix 3RV2 identifies the series; the sixth character encodes the nominal current—in this case, D corresponds to 3.2 A. The device is a three-pole thermal magnetic breaker with a rotary actuator and screw-type terminals, packaged as a box unit for DIN rail mounting.

Catalog Comparison
The 3RV2 series spans multiple current ratings in the same mechanical package. The primary difference across the first six alternates is the thermal-magnetic trip setting, which is fixed at the factory per the D-suffix coding.
| MPN | Current Rating | Similarity |
|---|---|---|
| 3RV24211DA10 | 3.2 A | — |
| 3RV24211CA10 | 2.5 A | 0.92 |
| 3RV24211EA10 | 4 A | 0.92 |
| 3RV24211FA10 | 5 A | 0.92 |
| 3RV24211GA10 | 6.3 A | 0.92 |
| 3RV24211HA10 | 8 A | 0.92 |
| 3RV24211JA10 | 10 A | 0.92 |
| 3RV24210KA10 | 1.25 A | 0.88 |
| 3RV24214DA10 | 25 A | 0.88 |
Why These Parts Are Similar
All nine parts share the same breaker type (thermal magnetic), actuator style (rotary), mounting (DIN rail), pole count (3P), and the full set of agency approvals. The alternates differ solely in the factory-set current rating, ranging from 1.25 A to 25 A. The 3RV24214DA10 and 3RV24210KA10 carry a similarity of 0.88 due to a one-character difference in the MPN suffix that affects frame-size classification.
FAQ
How does the 3RV24211DA10 coordinate with downstream contactors? The SIRIUS 3RV2 series is designed for direct assembly with corresponding 3RT2 contactors. The 3.2 A setting suits motor full-load currents in that range; coordination with contactors depends on the specific motor data and fault current conditions at the installation.
What terminal type does the 3RV24211DA10 use? The title and catalog entry specify screw-type connections. No spring-clamp or ring-lug option appears in the on-record specifications for this MPN.
Can the 3RV24211DA10 be used as a branch disconnect? Its multi-agency approvals (UL, CSA, CCC, VDE, CE, EAC) indicate suitability for branch circuit protection. The thermal magnetic characteristic provides both overload and short-circuit coordination.
