3VA5210-6EC31-0AA0 - HFAS 100 Amp Circuit Breaker

3VA5210-6EC31-0AA0 - HFAS 100 Amp Circuit Breaker

Not every job calls for something complicated. Sometimes you just need a breaker that’s going to trip when it should, stay out of the way when it shouldn’t—and hold up over time. That’s where the Siemens 3VA5210-6EC31-0AA0 fits in. This is a 100 amp, 3-pole breaker built on Siemens’ 3VA5 frame, and it’s made for standard three-phase systems you’ll see in commercial buildings and light industrial setups. It uses a thermal magnetic trip, so it reacts differently depending on the problem—slower for overloads, instant for faults. That’s exactly what you want in day-to-day operation. The settings are fixed, which a lot of guys actually prefer. 100A on the overload, 10x on the instantaneous—no tweaking, no second-guessing. Install it and move on. With a 35kA rating at 480V, it’s more than capable for most applications in its class. It’s not oversized, not undersized—it just lands right where most systems need it.
