3VA5240-6ED31-0AA0 - HFAS 40 Amp Circuit Breaker Description
3VA5240-6ED31-0AA0 - HFAS 40 Amp Circuit Breaker
The Siemens 3VA5240-6ED31-0AA0 is a straightforward 40 amp, 3-pole breaker built for three-phase systems.Nothing fancy here—and that’s the point. It’s made to protect your equipment and wiring without giving you extra setup work. It uses a thermal-magnetic trip, factory set at 40 amps. So there’s no adjusting or second-guessing. Once it’s in, it’s doing its job—handling overloads and tripping fast on short circuits. One thing worth noting is the interrupting rating. At 35kA @ 480V, it’s more than capable for most commercial and light industrial setups. When a fault hits, it clears it quickly, which helps avoid bigger damage downstream. If you’ve used Siemens 3VA breakers before, this one feels familiar. Same footprint, same general layout. Easy to work into existing panels or new installs.
