What this 3VA1 breaker carries
The Siemens 3VA1196-3ED32-0AA0-ZD00 is a 3-pole IEC frame 160 molded case circuit breaker with breaking capacity class N, meaning it delivers 25 kA Icu at 415 V AC — sufficient for most distribution and light motor branch circuits in commercial and industrial panels where the available fault current stays under that threshold. The FTFM designation indicates a fixed thermal, fixed magnetic trip — no field-adjustable dials, so the BOM must match the load exactly. The OEM designation does not restrict general distribution use; it is the same genuine Siemens part with a different passport.
For systems with higher available fault current, step up to class S or H frames in the 3VA family. The magnetic pickup at 320 A (20 × In) is high enough to avoid nuisance tripping on motor inrush but still protects against bolted faults. Mounts on standard DIN rail or panel-mount via the 3VA1 frame's integrated lugs. The nut keeper kit is already fitted, so no additional hardware is needed for the DC Power OEM application — saves a step in panel assembly.
