3VA5245-5ED31-0AA0 - MFAS 45 Amp Circuit Breaker Description
3VA5245-5ED31-0AA0 - MFAS 45 Amp Circuit Breaker
When you’re dealing with electrical systems, you don’t want to overthink your breaker—you just want something that works, trips when it should, and keeps everything protected. That’s exactly what you get with the Siemens 3VA5245-5ED31-0AA0. This is a 45 amp, 3-pole circuit breaker built for solid, everyday performance in commercial and industrial setups. It uses a thermal magnetic trip unit, which means it handles both overloads and short circuits the way you’d expect—no surprises. One thing people like about this model is that it’s factory set. The overload protection is fixed at 45 amps, and the instantaneous trip is set at 10 times that. So there’s no adjusting, no dialing things in—install it, and you’re good to go. It also brings a 35kA interrupting rating at 480V, which gives you the confidence to use it in higher fault environments without worrying about whether it can handle the job.
