3VA5217-7EC31-0AA0 - CFAS 175 Amp Circuit Breaker Description
3VA5217-7EC31-0AA0 - CFAS 175 Amp Circuit Breaker
The Siemens 3VA5217-7EC31-0AA0 is a 175 amp, 3-pole unit from the 3VA5 series, built for typical commercial and industrial work—panels, equipment, distribution. If you’ve worked with Siemens before, you already know what to expect here. It uses a thermal magnetic trip. That means it handles overloads and short circuits in a way that’s predictable and proven. Nothing fancy to dial in, nothing to babysit. Where this one really stands out is the interrupting rating—100kA at 480V. That gives you a lot more headroom in systems where available fault current is high. You’re not cutting it close. Install it, land your wires, and move on.
