Siemens 3VA5145-4ED32-0AA0 — SENTRON 3VA51 Three-Pole DIN-Rail Circuit Breaker
SENTRON 3VA51 Series Context (3VA5145-4ED32-0AA0)
The 3VA5145 prefix places this unit in Siemens' 3VA51 molded-case family, FTFM indicates feed-through/front-main connector terminations. The "-4ED32-0AA0" ordering code encodes the 45A rating (4ED), three-pole configuration (32), and nut-included packaging (0AA0). All 3VA51 units at this current rating share the same 25 kA interruption capacity and 480Y/277 V class designation. The lever actuator is the standard Siemens operator type for this frame size, with illumination not specified for standard FTFM variants.

Factory Terminal and Approval Differences
The "-4ED" segment defines the 45A frame with factory-terminated (FTFM) connectors; field termination is not required. Approval scope varies across the ordering code:
- 3VA5145-4ED32-0AA0 / 3VA5145-4ED22-0AA0: CCC, UL489 only
- 3VA5145-4ED36-0AA0 / 3VA5145-4ED36-1AA0: CCC, CE, UL489, VDE
- 3VA5145-4ED31-0AA0 / 3VA5145-4ED31-1AA0: CCC, CE, CSA, EAC, UL489, VDE; RoHS non-compliant noted
The 2-pole version (3VA5145-4ED22-0AA0) occupies the same frame width as a single pole of the 3-pole unit, enabling shared bus-bar mounting for reduced panel depth. One-pole variants (3VA5145-4ED12-0AA0, 3VA5145-4ED16-0AA0) use the same DIN clip cutout pattern across the series.
Comparative Selection (Alternates)
The reader must independently qualify the following alternates against the application requirements. Shared specs only; similarity does not imply fitness.
| Spec | 3VA5145-4ED32-0AA0 | 3VA5145-4ED36-0AA0 | 3VA5145-4ED31-0AA0 |
|---|---|---|---|
| Current Rating | 45A | 45A | 45A |
| Poles | 3 | 3 | 3 |
| Mounting | DIN Rail | DIN Rail | DIN Rail |
| Approvals | CCC, UL489 | CCC, CE, UL489, VDE | CCC, CE, CSA, EAC, UL489, VDE |
| Similarity | — | 1.0 | 1.0 |
- 3VA5145-4ED36-0AA0: Adds CE and VDE to the base approvals, matching the CCC and UL scope of the seed while extending CE compliance. Same 45A, three-pole, FTFM construction. Contrast: no CSA or EAC coverage versus the -31 variant.
- 3VA5145-4ED31-0AA0: Broadest approval set in this group (CCC, CE, CSA, EAC, UL489, VDE); includes EAC for Eurasian market access and CSA for Canadian requirements. RoHS non-compliant flagged, which may affect environmental compliance in certain installations.
