3VA5325-6EC31-0AA0 - 250A Class HJAS 3-Pole Circuit Breaker

3VA5325-6EC31-0AA0 - 250A Class HJAS 3-Pole Circuit Breaker

If you’re dealing with a system that can’t afford unexpected shutdowns, this Siemens 3VA5325-6EC31-0AA0 circuit breaker is built to handle the job. It’s a 250-amp, 3-pole breaker designed for solid, no-nonsense protection in commercial and industrial setups. At its core is a thermal magnetic trip unit, which means it reacts to both overloads and short circuits the way you’d expect—quickly and reliably. And with a 65 kA interrupting rating at 480V AC, it’s ready for higher fault conditions without hesitation. That’s the kind of protection that helps prevent equipment damage and keeps your operation running instead of troubleshooting. This model is part of Siemens’ 3VA5 series, known for being dependable without overcomplicating things. It’s straightforward, consistent, and does exactly what it’s supposed to do.
