3VA5240-5ED31-0AA0 - MFAS 40 Amp Circuit Breaker Description
3VA5240-5ED31-0AA0 - MFAS 40 Amp Circuit Breaker
Some breakers look good on paper but don’t hold up when it counts. This one does. The Siemens 3VA5240-5ED31-0AA0 is a straightforward, no-drama 40 amp, 3-pole circuit breaker built for real electrical systems—not lab conditions. You install it, it protects, and you move on. That’s the whole point. With a 35kA interrupting rating at 480V, it’s ready for serious fault conditions. The thermal magnetic trip handles both overloads and sudden shorts without needing constant tweaking. Everything is factory set, so there’s nothing to dial in or second-guess later. It’s part of the 3VA5 line, which a lot of contractors stick with for a reason—it’s consistent. No surprises, no weird behavior, just solid protection where you need it.
