The Siemens 3VA4135-5ED34-3AA0 is a 3-pole circuit breaker from the 3VA4 series, built on a UL Frame 125 footprint. The thermal-magnetic trip unit is a TM210, with a fixed overload setting at 35 A (Ir = 35 A) and a short-circuit pickup at 10 times the rated current (Ii = 10 x In). That 10x multiplier gives you a fast magnetic trip for hard faults while letting motor inrush or transformer energization ride through without nuisance tripping.
The packaging dimensions (472 x 396 x 213 mm) give you a sense of the shipping box, not the breaker itself — the 3VA4 frame is a standard panel-mount molded-case breaker, sized for a UL 125 A frame. The 3-pole configuration means it switches all three phases simultaneously, which is what you want for a three-phase motor branch circuit or a feeder tap.
RoHS compliance is confirmed from the 2019-05-13 production date forward, and the part contains lead (CAS-No. 7439-92-1) above the 0.1% threshold for REACH Article 33 notification. That's normal for the silver-alloy contacts in a breaker of this class — the lead is in the contact material, not a coating or a plasticizer.
