3VA5250-6ED31-0AA0 - HFAS 50 Amp Circuit Breaker
The Siemens 3VA5250-6ED31-0AA0 is a 50 amp, 3-pole breaker from the 3VA5 series. It’s a pretty standard option if you’re working with 480V three-phase and just need something reliable. It’s got a thermal magnetic trip, factory set. No adjustments. Overload is fixed at 50A, and the instantaneous trip is set at 10x. You drop it in, wire it up, and move on. Interrupting rating is 35kA at 480V, so it’ll handle most commercial applications without any issue. Nothing fancy here—and that’s kind of the point. It’s consistent, and it works.
