3VA4125-4ED34-0AA0 - 25Amp Circuit Breaker

3VA4125-4ED34-0AA0  -  25Amp Circuit Breaker

When you’re choosing a circuit breaker, you’re not looking for something flashy—you want something that works every time. The Siemens 3VA4125-4ED34-0AA0 is built with that exact mindset. It’s a straightforward, dependable molded case circuit breaker designed to protect your system without adding unnecessary complexity. This model features a 25A rating in a 125A frame, making it a solid choice for branch and line protection in commercial and industrial setups. It uses a thermal-magnetic trip unit (TM210), which means it handles both overloads and short circuits automatically—no fine-tuning required. And with a 25 kA interrupting capacity at 480V, it’s ready to respond when fault conditions hit, helping protect your equipment and reduce the risk of damage. One thing people like about this breaker is its simplicity. The trip settings are fixed, so once it’s installed, there’s nothing to adjust or second-guess. It just does its job. That’s especially valuable in environments where consistency matters and downtime costs money. If you’ve worked with Siemens equipment before, you already know what to expect—solid build quality and reliable performance over time. This breaker fits right into that reputation.
