3VA5220-7EF31-0AA0 - CFAS 200 Amp Circuit Breaker

3VA5220-7EF31-0AA0 - CFAS 200 Amp Circuit Breaker

When you're working with higher fault current, you don’t want to gamble on protection. The Siemens 3VA5220-7EF31-0AA0 is one of those breakers you install and move on—because you know it’s going to do its job. This is a 200 amp, 3-pole breaker from Siemens’ 3VA5 line, built for real-world commercial and industrial use. It carries a 100kA interrupting rating at 480V, which puts it in the category of breakers meant for tougher environments—where available fault current is high and failure isn’t an option. It uses a thermal magnetic trip unit (TM240), so you’re getting standard, reliable protection: overload protection locked in at 200A, and instantaneous trip at 10 times that. No adjustments, no extra setup. For a lot of applications, that’s exactly what you want—simple and predictable. Physically, it’s compact enough to fit comfortably in most panel setups without forcing you to rethink your layout. So you’re not trading space for performance.
