Key ratings and what they mean
The Siemens 3VA4195-4ED34-3AA0 is a 3-pole circuit breaker from the 3VA4 series, UL Frame 125, with a breaking capacity class S rated at 25 kA at 480 V. That 25 kA SCCR means it can safely interrupt a fault current up to that level without upstream devices needing to clear it — critical for panel coordination and avoiding cascading trips. The thermal-magnetic TM210 trip unit is set with a fixed overload protection Ir of 15 A (In=15 A) and a fixed short-circuit protection Ii of 20 x In (300 A). This fixed-trip configuration suits dedicated motor or feeder circuits where you don't need adjustable overloads — the breaker is sized exactly to the load's FLA.
Compliance and documentation
RoHS compliant since 13-05-19. REACH Article 33 duty to inform applies — the part contains lead (CAS-No. 7439-92-1) above 0.1% w/w, so downstream notification is required if the article is placed on the EU market. Export control classification is AL: N / ECCN: EAR99 — no special licensing needed for most destinations, but verify end-use if shipping to restricted entities.
Panel integration note
Mounts on a standard DIN rail in the enclosure. The 3-pole footprint fits a 125 A frame size; verify fill factor and thermal derating when grouping multiple breakers in a confined panel. Packaging dimensions are 472 x 396 x 213 mm — plan for incoming inspection and storage space.
