The 3VA5145-4ED26-0AA0 is a Siemens SENTRON FTFM (fixed thermal magnetic, frame-mounted) molded-case breaker rated 45 A, two poles, with lever actuator for DIN rail installation. The suffix positions encode terminal type and compliance markings rather than fundamental rating changes.
Design Trade-offs (Siemens 3VA51 Family)
- The FTFM platform uses a thermal-magnetic trip unit; users needing adjustable electronic protection must move to the 3VA5x electronic-trip variants within the same frame.
- Two-pole configuration provides single-phase protection but does not serve three-phase loads without additional pole count variants.
- Box encapsulation is standard; panel builders requiring conformal-coated or severe-environment versions must consult factory-rated variants (suffixes differ by market).
- UL489 and VDE/CCC listings coexist on most suffixes, but the 0AA0 base suffix carries only CCC and UL489 (CE and VDE are absent from some spec sheets); verify jurisdiction requirements before ordering.
- The 1AA0 suffix adds a "NAV" handle-color indicator for improved visibility in dense MCC bucket arrangements but does not alter interrupting rating.
Alternate Configurations (Siemens 3VA5145 Family)
The reader must independently verify that any alternate meets application requirements before selection.

- 3VA5145-4ED21-0AA0 / 3VA5145-4ED21-1AA0: Same 2-pole/45 A base, broader approval set (CSA, EAC added), but marked RoHS non-compliant; prefer when non-EU supply chains require CSA or EAC and RoHS status is not mandated.
- 3VA5145-4ED22-0AA0 / 3VA5145-4ED22-1AA0: 2-pole/45 A with reduced approval scope (CCC + UL489 only); suitable for markets where CE/VDE marking is not required and cost sensitivity is higher.
- 3VA5145-4ED26-1AA0: Functionally identical to the seed; the 1AA0 suffix changes handle indicator only and does not affect electrical performance.
