What this breaker is and what it does
The Siemens 3VA4111-6ED34-3AA0 is a 3-pole molded-case circuit breaker from the 3VA4 family, built on a UL Frame 125 footprint. It is rated for line protection with a TM210 thermal-magnetic trip unit. The continuous current rating In is 110 A, with overload protection Ir permanently set at 110 A and short-circuit protection Ii fixed at 10 × In (1100 A). The breaking capacity is class H: 65 kA at 480 V AC. That SCCR rating means it can safely interrupt fault currents up to 65,000 A without upstream cascading — a solid fit for high-available-fault-current industrial panels where standard 25 kA or 35 kA breakers would need a current-limiting fuse ahead of them.
Compliance and regulatory documentation
RoHS compliant since 13 May 2019. REACH Article 33 duty to inform applies: the part contains Lead (CAS-No. 7439-92-1) above 0.1% w/w in the current candidate list. Export control is AL: N / ECCN: EAR99, meaning no special licensing for most destinations.
