3VA5222-5EF31-0AA0 - MFAS 225 Amp Circuit Breaker Description
3VA5222-5EF31-0AA0 - MFAS 225 Amp Circuit Breaker
When you’re picking a circuit breaker, you’re not looking for anything fancy—you just want something that’s going to work when it needs to. The Siemens 3VA5222-5EF31-0AA0 is one of those breakers you install and don’t have to worry about again. It’s a 225 amp, 3-pole breaker made for three-phase systems, so it fits right into most commercial and industrial setups. The thermal magnetic trip unit keeps things simple. It handles overloads over time and trips instantly if there’s a short circuit. No complicated adjustments—just solid, predictable protection. With a 35kA interrupting rating at 480V, it’s built to deal with higher fault levels you’ll typically see in real-world applications. It’s also part of the Siemens 3VA5 series, which a lot of contractors stick with because it’s consistent and easy to work with across different jobs. Size-wise, it’s built on a 250 frame, so it doesn’t take up more space than it needs to. That makes a difference when you’re working inside a tight panel.
