3VA5222-7EF31-0AA0 - CFAS 225 Amp Circuit Breaker Description
3VA5222-7EF31-0AA0 - CFAS 225 Amp Circuit Breaker
The Siemens 3VA5222-7EF31-0AA0 is a 225 amp, 3-pole breaker built for typical commercial and industrial power setups. It’s part of the 3VA52 series, using a 250 frame, and it’s meant for line protection where you don’t need anything complicated—just something that works and holds up. This model comes with a thermal magnetic trip unit (TM240). Overload protection is fixed at 225A, and the instantaneous trip is set at 10x. There’s nothing to adjust, which makes installs quicker and avoids setup mistakes. Once it’s in, it’s ready. It’s rated 100kA at 480V, so it can handle higher fault levels without issue. That makes it a good fit for larger panels, distribution systems, or anywhere fault current is a concern. Size-wise, it’s pretty standard for this frame and doesn’t take up more space than expected.
