3VA5322-7EF31-0AA0 - 225A Class CJAS 3-Pole Circuit Breaker Description
3VA5322-7EF31-0AA0 - 225A Class CJAS 3-Pole Circuit Breaker
If you need a 225-amp, 3-pole circuit breaker that you can set and trust, the Siemens 3VA5322-7EF31-0AA0 is a solid, no-nonsense option. It’s part of the 3VA5 line, built on a 400A frame, and it’s meant for line protection in systems where things actually get used—not just spec’d on paper. It uses a thermal-magnetic trip, which is what most people are used to—nothing complicated, just reliable protection for overloads and short circuits. Where this one stands out a bit is the adjustability. You can set the overload anywhere from 180A up to 225A, and the instantaneous trip from 5x to 10x. That gives you enough range to match the breaker to your setup without fighting it. With a 100 kA rating at 480V, it’s also a good fit where available fault current is higher. This isn’t a light-duty piece—it’s meant for real distribution equipment.
