3VA5217-6EC31-0AA0 - HFAS 175 Amp Circuit Breaker Description
3VA5217-6EC31-0AA0 - HFAS 175 Amp Circuit Breaker
The Siemens 3VA5217-6EC31-0AA0 is the kind of breaker you use when you just need it to do its job—no tweaking, no babysitting, no surprises. It’s a 175 amp, 3-pole breaker built on the 3VA5 frame, designed for standard line protection in commercial and industrial systems. You’ve got a thermal magnetic trip unit, so it handles overloads and short circuits the way most electricians expect—nothing complicated, nothing hidden. The settings are fixed. Overload protection is locked at 175A, and the instantaneous trip hits at 10x that. That’s it. No adjustment dials to mess with, which honestly is a plus in a lot of installs. With a 35kA rating at 480V, it’s built to handle real fault conditions—not just light-duty panels. And the size is manageable, so you’re not fighting for space when you drop it into an existing setup.
