3VA5225-5EC31-0AA0 - MFAS 250 Amp Circuit Breaker Description
3VA5225-5EC31-0AA0 - MFAS 250 Amp Circuit Breaker
If you’re looking for a 250 amp circuit breaker that can handle real-world electrical demands without overcomplicating things, the Siemens 3VA5225-5EC31-0AA0 is a solid choice. This is a 3-pole thermal magnetic circuit breaker built for dependable protection in commercial and industrial environments. In plain terms—it watches your system for trouble and reacts fast when something’s off. Whether it’s a slow overload or a sudden short circuit, this breaker is designed to step in before damage spreads. What makes this model appealing is how straightforward it is. The overload protection is fixed at 250 amps, so there’s no guesswork during installation. And when a serious fault hits, the instantaneous trip (10x In) kicks in immediately to help limit equipment damage and downtime. With a 35kA interrupting rating at 480V, it’s capable of handling high fault currents you’d typically see in larger electrical systems. At the same time, it doesn’t take up more space than it needs to—making it a practical fit for panelboards, switchgear, and tight enclosures. Bottom line: this is the kind of breaker you install when you want reliable protection without constant adjustments or second-guessing.
