3VA5211-5EF31-0AA0 - MFAS 110 Amp Circuit Breaker Description
3VA5211-5EF31-0AA0 - MFAS 110 Amp Circuit Breaker
The Siemens 3VA5211-5EF31-0AA0 is a solid choice if you need a dependable 110 amp, 3 pole circuit breaker for a three-phase system. It’s built for real-world use—whether you’re working on a commercial panel, industrial equipment, or replacing an existing breaker. This model is part of the Siemens 3VA5 series, known for straightforward, reliable protection. It uses a thermal magnetic trip unit, which means it handles both overloads and short circuits without overcomplicating things. The 35kA interrupting rating at 480V gives you the confidence that it can deal with higher fault levels when they happen. What stands out here is its simplicity. The overload protection is fixed at 110 amps, and the instantaneous trip is set at 10 times the rated current. There’s nothing to tweak or second-guess—it just does its job. If you’re after a breaker that’s easy to install, predictable, and built to last, this one checks the boxes.
