The Siemens 3VA4111-6ED14-3AA0 is a 1-pole circuit breaker from the 3VA4 series, built on a UL Frame 125 platform. It carries a 65 kA interrupting rating at 277 V (breaking capacity class H), which means it can safely clear a fault up to that level on a 277 V line without upstream damage — a spec that matters for panel SCCR coordination. The TM210 thermal-magnetic trip unit is fixed at 110 A overload (Ir=110 A permanently set) with a short-circuit pickup of 10× In (Ii=10 x In), so it's sized for a 110 A continuous load and will hold through motor inrush up to roughly 1100 A before instantaneous trip.
Compliance & Regulatory
RoHS compliant since 13-05-19. Contains lead (CAS-No. 7439-92-1) above 0.1% w/w, so a REACH Article 33 duty-to-inform applies if the part is incorporated into an article placed on the EU market. Export Control Regulations: AL N / ECCN EAR99 — no special licensing required for most destinations.
Integration Note
Mounts on a DIN rail in a standard panel enclosure. The 1-pole form factor fits a single module width in the 3VA4 family. For a 110 A feeder on a 277 V line, verify that the panel SCCR rating is at least 65 kA at that voltage — this breaker is the interrupting device, not the withstand rating of the bus. Terminal lug sizing for 110 A should match the wire gauge range in the installation instructions.
