3VA5325-7EC31-0AA0 - 250A Class CJAS 3-Pole Circuit Breaker

3VA5325-7EC31-0AA0 - 250A Class CJAS 3-Pole Circuit Breaker

The Siemens 3VA5325-7EC31-0AA0 is a 250A, 3-pole circuit breaker built for everyday use in commercial and industrial systems. It’s part of the 3VA5 series and uses a 400A frame, which gives you some flexibility if your setup changes down the line. This model uses a thermal magnetic trip unit, so it handles overloads and short circuits the way most electricians expect—nothing complicated, just reliable protection. The overload is fixed at 250 amps, and the instantaneous trip can be adjusted between 5 and 10 times the rated current. That helps when you’re trying to line it up with other protective devices in the system. With a 100 kA interrupting rating at 480V AC, it’s designed to deal with higher fault levels without hesitation. That makes it a solid fit for heavier-duty applications where smaller breakers just won’t cut it.
