What it is and what it does
The Siemens 3VA4110-6ED24-3AA0 is a 2-pole molded case circuit breaker from the 3VA4 series, UL Frame 125, rated for line protection. It carries a breaking capacity of 65 kA at 480 V (class H), meaning it can safely interrupt a fault current up to that level without damage to downstream equipment — critical for high-fault installations like industrial panel mains or feeder circuits. The thermal-magnetic trip unit (TM210) provides fixed overload protection at 100 A (Ir=100 A permanently set) and short-circuit protection at 10× In (Ii=10× In). That fixed overload setting simplifies panel design — no field adjustment, no calibration drift.
