3VA5325-7EF31-0AA0 - 250A Class CJAS 3-Pole Circuit Breaker

3VA5325-7EF31-0AA0 - 250A Class CJAS 3-Pole Circuit Breaker

When you’re putting together a panel or replacing a breaker, you don’t want surprises—you want something that fits, performs, and holds up. The Siemens 3VA5325-7EF31-0AA0 is a straightforward 250-amp, 3-pole breaker designed for that exact purpose. It’s part of the 3VA5 line, which is widely used in commercial and industrial setups because it’s reliable without being complicated. This model uses a thermal magnetic trip unit, so it reacts the way you’d expect: it handles gradual overloads and trips fast when there’s a short circuit. The adjustable overload setting (200A to 250A) is a nice touch—it gives you some flexibility when you’re matching it to your system instead of forcing you into a fixed number. It’s built on a 400A frame, so there’s some headroom there, and it’s rated for higher fault conditions with its Class C interrupting capability. Overall, it’s a solid, no-nonsense option for keeping your system protected.
