3VA5210-7EC31-0AA0 - CFAS 100 Amp Circuit Breaker Description
3VA5210-7EC31-0AA0 - CFAS 100 Amp Circuit Breaker
The Siemens 3VA5210-7EC31-0AA0 is a straightforward, high-capacity breaker for jobs where lower-rated units just won’t cut it. If you’re working in a system with higher available fault current, this is the kind of breaker you spec so you don’t have to worry about it later. It’s rated at 100 amps with a 100 kA interrupting capacity at 480V, which puts it in the range for more demanding commercial and industrial applications. The thermal magnetic trip unit keeps things simple—overload protection is fixed at 100A, and short-circuit protection kicks in at 10 times that. No adjustments, no fine-tuning. Install it and move on. The 3VA52 frame is also a nice middle ground. It’s compact enough to work into tighter panel spaces but still built for heavier-duty applications. Whether you’re replacing a failed breaker or building out a new panel, it’s a solid, no-nonsense option.
