What this breaker is and what the ratings mean for your panel
The Siemens 3VA4135-4ED34-3AA0 is a 3-pole molded case circuit breaker from the 3VA4 series, built on a UL Frame 125 footprint. Its headline rating is 35 A continuous current with a 25 kA interrupting capacity at 480 V — that's the fault current it can safely clear without welding contacts or rupturing the case, sized for commercial and light industrial panelboards where available fault current stays under that threshold.
Active production and what that means for sourcing
Because it's made to order, we source and quote it against an RFQ. Availability and current pricing are confirmed at quote time through our independent distribution channels. If you're freezing a BOM or filling a line-down replacement, send the order code and quantity — we'll come back with a firm number and ship window.
Panel integration notes
Mounts on a DIN rail or direct-panel via the frame's bolt-on lugs — the 3VA4 UL Frame 125 footprint is standard for 125 A frame breakers, so it fits existing cutouts and busbar arrangements in most UL 508A panels. The packaging dimensions (472 × 396 × 213 mm) give you a shipping box size, but the breaker itself is compact enough for a 12-inch-wide enclosure with room for branch wiring.
