3VA5322-6EC61-0AA0 - 225A Class HJAS 2-Pole Circuit Breaker

When you’re dealing with power distribution, you don’t want surprises. The Siemens 3VA5322-6EC61-0AA0 is the kind of circuit breaker you install and don’t have to think about again—it just does its job. Built for commercial and industrial use, this 225-amp breaker protects your system from overloads and short circuits without overcomplicating things. It uses a thermal magnetic trip unit (TM230), which means it reacts to long-term overloads and sudden faults the way you’d expect. The overload protection is fixed at 225A, so there’s no guesswork there, while the instantaneous trip can be adjusted between 5–10 times the rated current. That gives you a bit of control when you need it, especially in systems with varying startup loads or inrush currents. One thing people like about this model is the configuration—it’s a 2-pole breaker in a 3-pole frame. That might sound minor, but it makes a difference when you’re trying to fit equipment into an existing panel or keep things consistent across installs. It’s also rated for up to 65 kA at 480V AC (Class H), so it’s ready for environments where fault levels can get high.

Key Features and Benefits
