The 3VA52 family covers frame sizes in the SENTRON line; the FTFM suffix designates front-terminal flat-bar (mechanical) termination for use with bus or cable connections. The NUT variant includes factory-installed mounting hardware for the terminal nut assembly.
Compare: Seed vs Catalog Alternates
The reader must independently qualify the following alternatives against application requirements. Similarity scores reflect catalog-parameter proximity only and do not constitute interchangeability or approval equivalence.

- 3VA5217-5ED32-1AA0: Shares 3-pole / 175 A / DIN Rail; differs by omitting CSA; ships with
NAVlabel designation (visual indicator variant). - 3VA5217-5ED36-0AA0: Matches seed on poles, rating, and approvals;
ALsuffix indicates aluminum terminal material instead of copper-alloy flat bar. - 3VA5217-5ED31-0AA0: Retains 3-pole / 175 A / DIN Rail; carries additional EAC and VDE certifications and is flagged RoHS non-compliant.
3VA52 Family Pole-Count and Certification Variants
The 3VA52 series uses a structured MPN scheme where digit positions encode pole count and approval bundle. Panel builders selecting based on branch-circuit count should cross-reference the specific suffix against local authority requirements.
- 4-pole variant: 3VA5217-5ED41-0AA0 extends to four poles while retaining 175 A and DIN Rail mounting; useful for three-phase with neutral protection or ground-fault coordination.
- 2-pole variant: 3VA5217-5ED61-0AA0 provides a 2-pole option in the same frame, suitable for single-phase loads within the same current and short-circuit ratings.
- FTAM base variant: 3VA5217-5EC32-0AA0 shares the 175 A / 3-pole / DIN Rail profile with
FTAMfront-terminal alternative mounting configuration; check mechanical dimensions for existing panel layouts.
Selection Criteria for SENTRON Frame Sizing
Rated current of 175 A places the 3VA52 at the upper end of standard DIN-rail-compatible molded-case breakers. Thermal-magnetic trip units handle typical industrial distribution loads; verify coordination with upstream protective device and downstream cable ampacity. Frame thermal ratings assume ambient conditions per UL 489; enclosed panel temperatures may require derating per Siemens derating curves.
