The reader must qualify all alternate MPNs against application requirements independently. Similarity values reflect catalog-parametric proximity only and do not indicate interchangeability.
Why these alternates are similar
All listed parts share the 3VA51 family frame, 125A rating, three-pole configuration, and DIN Rail mounting form factor. Divergence occurs in approval coverage (some variants carry CSA/EAC, others omit VDE), RoHS status (suffix "-31xx" entries are non-compliant), or terminal type (dash-0 suffix versus dash-1 suffix indicates nut-versus-box lug or similar termination difference per Siemens 3VA5x internal coding conventions). Poles-differing alternates (single-pole -6ED16, two-pole -6ED26) are included to represent the 3VA51 series breadth but require separate branch-circuit qualification.
Key Specifications (3VA5112-6ED36-1AA0)
| Parameter | Value |
|---|---|
| Current Rating | 125A |
| Breaking Capacity (Icu) | 65 kA |
| Number of Poles | 3 |
| Actuator Type | Lever |
| Mounting | DIN Rail (35 mm) |
| Illumination | None |
| Encapsulation | Box |
| Package | Box |
| Approvals | CCC, CE, UL489, VDE |
| Series | SENTRON |
| Product Status | Active |
The 65 kA short-circuit rating places this breaker in the high-interrupting-capacity class suitable for motor feeder or transformer-protective applications in installations requiring VDE and UL489 dual-listing. The lever actuator supports manual trip and reset.
Engineering Verification Checklist
- Confirm 125A frame rating matches calculated branch load (NEC Article 430 or applicable standard)
- Verify 65 kA Icu exceeds available prospective short-circuit current at line terminals
- Confirm DIN Rail mounting envelope and clearance per Siemens 3VA5x dimensions
- Validate terminal torque specification for box-lug termination per Siemens instruction sheet
- Confirm three-pole configuration suits three-phase supply system (415 V AC typical for 3VA51)
- Verify applicable approval agencies match the installation jurisdiction (CCC for China, VDE for Germany/EU, UL489 for US/Canada)
- Check series SENTRON accessories compatibility if downstream protection or signaling is required
- Confirm illumination is not required; the part offers none
- Verify enclosure ventilation or heat dissipation accounts for 125A thermal load
