3VA5280-6EF31-0AA0 - HFAS 80 Amp Circuit Breaker Description
3VA5280-6EF31-0AA0 - HFAS 80 Amp Circuit Breaker
If you’re looking for a circuit breaker that does its job—no fuss, no surprises—the Siemens 3VA5280-6EF31-0AA0 is a solid pick. It’s an 80-amp, 3-pole breaker built for real-world electrical systems where reliability isn’t optional. Whether you’re protecting equipment in a commercial building or keeping an industrial setup running, this one is designed to react fast when something goes wrong. It uses thermal magnetic protection, which means it handles both overloads and short circuits without any complicated components. And with an interrupting rating of 35kA at 480V (and up to 65kA in Class H conditions), it’s more than capable in environments where fault levels are high. You’re not squeezing it into a light-duty role—it’s made for serious work. Another thing worth mentioning: it’s straightforward. The trip settings are fixed (Ir at 80A and instantaneous at 10x), so there’s no time wasted dialing things in. Install it, wire it, and move on. The size is also reasonable for a breaker in this class so that it won’t crowd your panel more than necessary.
