The Siemens 3VA4150-4ED24-3AA0 is a 2-pole circuit breaker from the 3VA4 series, built on a UL Frame 125 platform. It's rated for line protection with a TM210 trip unit, fixed at 50 A overload protection (Ir = 50 A) and a short-circuit pickup of 10 × In (Ii = 10 × 50 A = 500 A). The breaking capacity lands at 25 kA at 480 V, placing it in Siemens' class S for this frame size — enough for most downstream panel feeders and branch circuits in North American 480 V distribution.
