3VA5225-5EF31-0AA0 - MFAS 250 Amp Circuit Breaker
If you’re just looking for a solid 250-amp breaker that will do its job without giving you trouble, this is it. The Siemens 3VA5225-5EF31-0AA0 is a 3-pole unit rated at 35kA @ 480V, so it’s more than capable for most commercial and light industrial applications. It uses a standard thermal magnetic trip—nothing complicated—so it handles overloads and short circuits the way you’d expect. Everything is factory set. Overload is locked at 250A, and the instantaneous trip is set at 10x. No adjustments, no guesswork. Install it and move on. It’s also part of the newer 3VA5 frame, which is a bit more compact than older breakers. That helps when you’re dealing with tighter panels or replacing existing gear.
