3VA5245-6ED31-0AA0 - HFAS 45 Amp Circuit Breaker Description
3VA5245-6ED31-0AA0 - HFAS 45 Amp Circuit Breaker
The Siemens 3VA5245-6ED31-0AA0 is a straightforward, no-nonsense 45-amp circuit breaker built for everyday commercial and industrial use. If you need reliable protection on a 480V system without overthinking it, this one checks the box. It’s a 3-pole breaker, so you’re covering all phases, and it uses a thermal magnetic trip unit. That means it handles overloads over time and reacts quickly when there’s a short circuit. Nothing complicated—just the kind of protection most systems are designed around. With a 35kA interrupting rating, it’s capable of handling higher fault conditions safely. That gives you some breathing room in tougher applications where fault current is a concern. It’s also part of Siemens’ 3VA5 series, which is widely used and easy to work with. The size is manageable, the setup is simple, and once it’s in place, it does what it’s supposed to do.
