3VA4112-4ED34-0AA0 - 125Amp Circuit Breaker

3VA4112-4ED34-0AA0  -  125Amp Circuit Breaker

If you need a 125 amp circuit breaker you can rely on without second-guessing, the Siemens 3VA4112-4ED34-0AA0 is a solid choice. Built for real-world electrical systems, this 3-pole molded case circuit breaker is designed to protect your equipment and keep your operation running smoothly. It’s part of Siemens’ trusted 3VA4 series, known for consistent performance in commercial and industrial environments. This model uses a TM210 thermal-magnetic trip unit, which means it handles both overloads and short circuits in a simple, dependable way. The overload protection is factory-set at 125A, so there’s nothing to adjust, and the magnetic trip reacts quickly at higher fault levels (10x In) to help prevent damage. With a 25 kA interrupting rating at 480V, this breaker is well-suited for systems where higher fault currents are a concern. Whether it’s installed in a panelboard or feeding critical equipment, it’s built to do its job without unnecessary complexity.
