3VA5217-5ED31-0AA0 - MFAS 175 Amp Circuit Breaker

When you’re dealing with real electrical loads—not theory, not lab conditions—you want a breaker that just works without drama. The Siemens 3VA5217-5ED31-0AA0 is built for that kind of job. This is a 175 amp, 3-pole molded case circuit breaker from Siemens’ 3VA5 line. It’s designed to handle everyday demands in commercial and industrial setups while still reacting fast when something goes wrong. With a 35kA interrupting rating at 480V, it’s ready to shut things down safely if a fault hits. One thing people like about this model—it’s not complicated. The thermal-magnetic trip unit is factory set, so you’re not spending time dialing things in or second-guessing settings. You install it, and it does what it’s supposed to do.
