Ratings and protection profile
The 3VA4125-4ED24-3AA0 is a 2-pole molded case circuit breaker from the Siemens 3VA4 UL Frame 125 series, sized for line protection in 480 VAC panels. Overload protection is fixed at 25 A (Ir = 25 A, TM210 thermal-magnetic trip), with short-circuit pickup fixed at 12 times In (300 A instantaneous). No dials or adjustment bands — what you see on the nameplate is what the circuit sees. That makes it a straight drop-in for a BOM that calls out a 25 A fixed-trip MCCB.
Note the product class: it is manufactured or produced to order, which means it is not a stocked shelf item. Export controls are straightforward: AL N / ECCN EAR99, so no special licensing for most destinations.
RoHS compliant since May 13, 2019.
