3VA5222-7EC31-0AA0 - CFAS 225 Amp Circuit Breaker Description
3VA5222-7EC31-0AA0 - CFAS 225 Amp Circuit Breaker
If you're working with higher loads and tighter tolerances, you already know—this isn't the place to cut corners. The Siemens 3VA5222-7EC31-0AA0 is a 225A, 3-pole breaker that's built for real-world use in commercial and industrial systems where failure isn't an option. This model uses a thermal magnetic trip unit (TM230), which keeps things simple. No complicated adjustments—overload protection is fixed at 225A, and the instantaneous trip is set at 10x that. It does exactly what it's supposed to do: react quickly when something goes wrong and stay out of the way when everything's running normally. The 100kA rating at 480V is what makes it a solid choice for higher fault environments. That kind of capacity gives you breathing room in systems where available fault current is no joke. Physically, it's part of the 3VA5 line with a 250 frame, so it fits where you'd expect and installs without surprises.
