3VA5220-5EC31-0AA0 - MFAS 200 Amp Circuit Breaker

3VA5220-5EC31-0AA0 - MFAS 200 Amp Circuit Breaker

If you need a 200-amp, 3-pole circuit breaker you can install and forget, this Siemens 3VA5220-5EC31-0AA0 is a solid pick. It’s part of the 3VA52 line, which many people stick with because it’s simple and consistent. No complicated setup, no extra adjustments. This one uses a thermal magnetic trip, so it handles overloads and short circuits the way you’d expect—automatically. The settings are fixed at 200A, which actually makes life easier in most installs since there’s nothing to tweak or misconfigure. Where it really matters is fault protection. With a 35kA interrupting rating at 480V, it’s built to deal with higher fault levels you’ll see in commercial panels or light industrial setups. That’s the kind of spec that gives you some breathing room when things go sideways. It’s also fairly compact for a 250 frame breaker, so it fits into tighter panels without a fight. If you’ve ever had to make space in a crowded enclosure, you know that’s not a small thing.
