3VA5270-5ED31-0AA0 - MFAS 70 Amp Circuit Breaker

3VA5270-5ED31-0AA0 - MFAS 70 Amp Circuit Breaker

If you just need a breaker that does its job without causing problems later, this Siemens 3VA5270-5ED31-0AA0 is a safe bet. It’s a 70 amp, 3-pole unit made for three-phase systems, and it’s built to handle the kind of loads you typically see in commercial and light industrial setups. It uses a standard thermal magnetic trip. Nothing fancy—but that’s the point. It handles overloads the way it should, and if there’s a short circuit, it trips fast. The settings are fixed at 70A, so there’s no adjusting or second-guessing. Install it, wire it, and move on. The 35kA interrupting rating at 480V gives you a decent cushion for fault conditions. That’s usually what people are looking for in this range—something that won’t come up short when it actually matters. It’s also part of the Siemens 3VA5 line, which is pretty common in the field. So if you’ve worked with these before, you already know what you’re getting.
