3VA5222-7ED31-0AA0 - CFAS 225 Amp Circuit Breaker

3VA5222-7ED31-0AA0 - CFAS 225 Amp Circuit Breaker

If you’re working with higher fault levels and need a breaker you don’t have to second-guess, the Siemens 3VA5222-7ED31-0AA0 is built for exactly that kind of job. This 225 amp, 3-pole unit from the 3VA52 series is designed for solid, consistent protection in commercial and industrial setups where reliability isn’t optional. What stands out here is the 100kA interrupting rating at 480V—that gives you the confidence to handle serious fault conditions without worrying about failure. The built-in thermal magnetic trip unit (TM210) keeps things straightforward: dependable overload protection paired with fast response to short circuits. No unnecessary complexity, just protection that does what it’s supposed to do. It’s also sized to fit comfortably into most panel configurations without eating up space, which makes it a practical choice whether you’re replacing an existing unit or building out a new system.
