3VA5217-6ED31-0AA0 - HFAS 175 Amp Circuit Breaker

3VA5217-6ED31-0AA0 - HFAS 175 Amp Circuit Breaker

The Siemens 3VA5217-6ED31-0AA0 is the kind of breaker you install and don’t have to worry about again. It’s a 175-amp, 3-pole unit from the 3VA5 line, built for standard three-phase protection in commercial and industrial applications. This model uses a thermal magnetic trip (TM210), which is about as straightforward as it gets. Overload protection is fixed at 175 amps, and the instantaneous trip is set at 10 times that. In other words, it reacts fast when something goes wrong, without needing any field adjustments or fine-tuning. It also carries a 35 kA interrupting rating at 480V so that it can handle higher fault currents without hesitation. For most applications, that means you’re covered when it matters. Physically, it’s compact for its class and fits well into typical panel layouts using the 3VA52 frame—no surprises on install.
