3VA5215-7EC31-0AA0 - CFAS 150 Amp Circuit Breaker

3VA5215-7EC31-0AA0 - CFAS 150 Amp Circuit Breaker

The Siemens 3VA5215-7EC31-0AA0 is the kind of breaker you use when you just want it handled—no tweaking, no second-guessing. It’s a 150 amp, 3-pole unit built for solid, everyday protection in commercial and industrial systems, with a 100kA interrupting rating at 480V to deal with serious fault conditions when they show up. This one comes with a thermal magnetic trip unit, so overloads and short circuits are covered in a straightforward way. The settings are fixed—overload is locked at 150A and the instantaneous trip is set at 10x that. That’s intentional. It keeps things predictable and avoids the “did someone adjust this?” problem you run into on job sites. It’s part of Siemens’ 3VA5 line (250 frame), which is known for being compact and easy to work with. Not oversized, not awkward—just a clean fit in most panels without fighting for space.
