3VA5215-6EC31-0AA0 - HFAS 150 Amp Circuit Breaker

If you’ve worked with Siemens gear before, you already know what to expect here. The 3VA5215-6EC31-0AA0 is a 150-amp, 3-pole breaker that’s built to protect your system without overcomplicating things. It uses a thermal magnetic trip unit, so you’re covered on both overloads and short circuits. Nothing fancy to dial in—settings are fixed from the factory, which honestly saves time and avoids mistakes during install. This one sits in the 3VA5 frame, so it’s compact for what it delivers. You still get a strong interrupting rating, but it won’t eat up unnecessary space in your panel. That makes it a good fit whether you’re swapping out a failed breaker or putting together something new. At the end of the day, it’s just a solid, dependable breaker. The kind you install and move on.
