Why These Parts Are Similar
3VA5145-4ED31-1AA0 — shares the same 3VA51 prefix, lever actuator, DIN Rail mounting, and 45A three-pole configuration. The approval list extends to include CE, CSA, EAC, and VDE, and the RoHS field shows non-compliant status; the primary part record does not carry a RoHS value.
3VA5145-4ED36-1AA0 — matches on pole count, current rating, actuator type, mounting, and series. Approvals include CE and VDE in addition to the CCC and UL489 carried on the primary part.
3VA5145-4ED12-1AA0 and 3VA5145-4ED22-1AA0 — share the series designation, actuator type, mounting, and current rating; they differ in pole count (1-pole and 2-pole respectively), representing the lower pole-count variants within the same family ordering logic.

Additional In-Catalog Variants
The following two parts share the same pole count, current rating, and family logic but differ in terminal configuration suffix:
- 3VA5145-4ED36-0AA0 — 3-pole, 45A, lever, DIN Rail, CCC/CE/UL489/VDE approvals; differs in terminal type suffix (0 vs 1).
- 3VA5145-4ED31-0AA0 — 3-pole, 45A, lever, DIN Rail, CCC/CE/CSA/EAC/UL489/VDE approvals; RoHS non-compliant.
Both carry a similarity score of 1.00 relative to the primary part; the primary part record contains no RoHS entry.
Ordering Context
The 3VA51 prefix identifies the Siemens SENTRON series of DIN-rail-mounted molded-case circuit breakers used for branch and feeder protection in commercial and industrial distribution panels. The digit positions in the full MPN encode voltage class, interrupting rating, and terminal/fitted device options. Panel builders and specifiers selecting this device should confirm that the 45A frame, three-pole configuration, and applicable approval agencies (CCC, UL489) align with the target installation's coordinating protection scheme and jurisdictional requirements.
