3VA5210-5ED31-0AA0 - MFAS 100 Amp Circuit Breaker

3VA5210-5ED31-0AA0 - MFAS 100 Amp Circuit Breaker

If you’re replacing a breaker or building out a panel, you probably want something simple: install it, trust it, and move on. That’s exactly where the Siemens 3VA5210-5ED31-0AA0 fits in. This is a 100 amp, 3-pole circuit breaker built for three-phase systems you see every day in commercial and industrial work. It’s part of Siemens’ 3VA5 series, which has a solid reputation for being consistent and easy to work with. There’s nothing complicated here—and that’s a good thing. It uses a thermal magnetic trip unit, so it handles overloads and short circuits the way most techs expect. The settings are already dialed in at the factory, so you’re not spending extra time adjusting anything. Install it, wire it, and you’re good. Where it really matters is protection. With a 35kA interrupting rating at 480V, this breaker is built to clear higher fault currents without hesitation. That helps protect your equipment—and avoids the kind of downtime nobody wants to deal with. It’s also sized right. The 3VA52 frame keeps things compact enough to fit into standard panels without fighting for space.
