3VA5211-5ED31-0AA0 - MFAS 110 Amp Circuit Breaker

3VA5211-5ED31-0AA0 - MFAS 110 Amp Circuit Breaker

The Siemens 3VA5211-5ED31-0AA0 is a straightforward breaker that does exactly what you expect—protect your system and stay out of the way when everything’s running normally. It’s a 110 amp, 3-pole unit from the Siemens 3VA5 line, built for typical commercial and light industrial use. Nothing overly complicated here. You install it, wire it up, and it handles overloads and short circuits without needing constant attention. With a 35kA rating at 480V, it’s more than capable for most standard applications where fault current is a real concern. And since it uses a thermal magnetic trip (TM210), you’re getting a setup that’s been used for years because it works. The overload protection is set to 110 amps—no adjustments to mess with. For short circuits, it trips instantly at 10x the rated current. Simple and predictable.
