3VA5211-5EC31-0AA0 - MFAS 110 Amp Circuit Breaker Description
3VA5211-5EC31-0AA0 - MFAS 110 Amp Circuit Breaker
If you’ve worked with Siemens 3VA breakers before, you already know the appeal—simple, reliable, and built to handle everyday electrical demands without fuss. The Siemens 3VA5211-5EC31-0AA0 is a 110 amp, 3 pole circuit breaker designed for solid performance in commercial and industrial power distribution systems. With a 35kA interrupting rating at 480V, this breaker is ready to clear fault conditions quickly and keep your equipment protected. It uses a thermal magnetic trip unit (TM230) with fixed settings, which means no field adjustments and no guesswork. Once it’s installed, it does exactly what it’s supposed to do—trip when it should, and stay out of the way when it shouldn’t. This is the kind of breaker you choose when you want consistency. It’s compact enough to fit comfortably in modern panels, but still delivers the protection you expect from the Siemens 3VA5 series.
