What this breaker is and where it fits
The Siemens 3VA4150-6ED24-3AA0 is a 2-pole molded-case circuit breaker in the 3VA4 platform, built on a UL Frame 125 footprint. It carries a 65 kA interrupting rating at 480 V — class H breaking capacity — meaning it clears high-fault currents in a 480 VAC distribution panel without upstream coordination issues. The TM210 thermal-magnetic trip unit is set at In=50 A; overload protection Ir is permanently locked at 50 A, and short-circuit pickup Ii is fixed at 10x In (500 A). This is a line-protection breaker sized for a 50 A feeder or a 50 A-rated load in a UL 489 panelboard.
