3VA5210-7ED31-0AA0 - CFAS 100 Amp Circuit Breaker Description
3VA5210-7ED31-0AA0 - CFAS 100 Amp Circuit Breaker
Some breakers are just spec-sheet fillers. This isn’t one of them. The Siemens 3VA5210-7ED31-0AA0 is built for situations where fault current isn’t small—and mistakes get expensive fast. You’re looking at a 100A, 3-pole breaker with a 100kA interrupting rating at 480V, which puts it in a category you typically use for serious commercial or industrial work. What most people like about this model? It keeps things simple. The thermal-magnetic trip unit (TM210) comes with fixed settings. No dialing things in, no second-guessing. Overload is locked at 100A, and short-circuit protection trips at 10x that. It does exactly what it’s supposed to do—nothing fancy, nothing unpredictable. Physically, it’s part of Siemens’ 3VA5 frame family (Frame 250), so it’s compact enough to work into tight panel layouts without becoming a problem. If you’ve worked in crowded gear before, you already know how much that matters. This is the kind of breaker you install and move on. It just sits there and does its job.
