3VA5211-7EC31-0AA0 - CFAS 110 Amp Circuit Breaker Description
3VA5211-7EC31-0AA0 - CFAS 110 Amp Circuit Breaker
The Siemens 3VA5211-7EC31-0AA0 is a 110-amp, 3-pole breaker built for systems where fault current is no joke. With a 100kA rating at 480V, it’s meant for applications that require serious interruption capacity—not just basic protection. It uses a thermal-magnetic trip unit (TM230). No adjustments here. The overload is fixed at 110A, and the instantaneous trip is set at 10x that. Simple setup. Fewer variables. That’s usually what you want in the field. This is part of the 3VA5 line, which many people stick with once they’ve used it. It’s consistent. It fits where it’s supposed to. And it doesn’t create extra work during install. Size-wise, it’s compact enough for most panel configurations, but still built for heavier-duty use. Good fit for both new builds and replacements.
