3VA5217-7ED31-0AA0 - CFAS 175 Amp Circuit Breaker Description
3VA5217-7ED31-0AA0 - CFAS 175 Amp Circuit Breaker
The Siemens 3VA5217-7ED31-0AA0 is the kind of breaker you install and don’t have to think about again. It’s rated at 175 amps and built to handle serious fault conditions, with a 100kA interrupting rating at 480V—so when something goes wrong, it reacts fast and does what it’s supposed to do. This model uses a thermal magnetic trip unit, which is still the go-to choice for a lot of contractors and facility guys because it’s predictable and proven. Overload protection is fixed at 175A, and the instantaneous trip is set at 10 times that. No tweaking, no guesswork—just install it and move on. It’s part of Siemens’ 3VA5 line, and if you’ve worked with these before, you already know the deal: solid build, consistent performance, and no unnecessary complications.
