3VA5222-6EC31-0AA0 - HFAS 225 Amp Circuit Breaker

3VA5222-6EC31-0AA0 - HFAS 225 Amp Circuit Breaker

The Siemens 3VA5222-6EC31-0AA0 is a 225 amp, 3-pole breaker made for standard three-phase power setups. Nothing complicated here—it’s a thermal magnetic unit with fixed settings, so you’re not spending time dialing things in. It’s built to trip when it should, plain and simple. Overload protection is locked at 225 amps, and the instantaneous trip is set at 10x that. That’s pretty typical for this kind of breaker, and it works well for most commercial and light industrial applications. If there’s a fault, it reacts fast and helps protect the rest of the system. It’s rated for 35kA at 480V, which gives you a decent safety margin in higher fault conditions. Physically, it’s not oversized either, so it fits into panels without much trouble. If you’ve worked with Siemens 3VA5 breakers before, this one will feel familiar.

Where It Works Best
