3VA5280-6EC31-0AA0 - HFAS 80 Amp Circuit Breaker Description
3VA5280-6EC31-0AA0 - HFAS 80 Amp Circuit Breaker
If you’re working with a 3-phase system and need a breaker that just does its job without fuss, the Siemens 3VA5280-6EC31-0AA0 is a solid pick. Rated at 80 amps with a 35kA interrupting capacity at 480V, it’s built for dependable line protection in commercial and light industrial setups. This unit uses a thermal magnetic trip (TM230), which means it reacts properly to both overloads and sudden faults—no guesswork, no complicated setup. What makes this one practical is its fixed settings. The overload protection is locked in at 80A, and the short-circuit trip kicks in at 10 times the rated current, so you’re getting consistent, predictable protection right out of the box. No adjustments needed. Just install it and move on. The 3VA52 frame (UL 250 frame size) keeps things compact enough to fit comfortably into most panel configurations, without sacrificing performance where it counts.
