3VA5322-5EC61-0AA0 - 225A Class MJAS 2-Pole Circuit Breaker

The Siemens 3VA5322-5EC61-0AA0 is a 225-amp breaker built for everyday commercial and industrial use. Nothing fancy here—and that’s the point. It’s designed to protect your system, trip when it should, and keep things moving. It uses a thermal magnetic trip unit, so overloads and short circuits are handled the way most techs expect. This model also comes with fixed settings, which means no adjustments and no guesswork. Install it, wire it, and you’re done. It’s a 2-pole breaker in a 3-pole frame, which can help when you’re working within existing panel layouts or trying to match what’s already there.
