3VA4125-6ED34-0AA0 - 25Amp Circuit Breaker

3VA4125-6ED34-0AA0  -  25Amp Circuit Breaker

When you're working with electrical systems, reliability isn’t something you think about—it’s something you expect. The Siemens 3VA4125-6ED34-0AA0 circuit breaker is built with that mindset. It’s a straightforward, dependable solution for protecting three-phase power systems in commercial and industrial environments. This model is rated at 25 amps and offers a 65 kA interrupting capacity at 480V, so it’s well-equipped to handle high fault conditions without putting your equipment at risk. Whether it’s installed in a panelboard, feeding downstream equipment, or part of a larger distribution setup, it does its job quietly and consistently. One of the things contractors and engineers like about this breaker is its thermal-magnetic trip unit (TM210). The settings are fixed—25A for overload protection and 12x instantaneous trip—which means there’s no need for adjustment or calibration. You install it, and you know exactly how it’s going to respond. That kind of predictability saves time and avoids mistakes. It’s also built on Siemens’ 125 frame platform, giving you a compact footprint that fits well in tighter panel spaces without sacrificing performance.
