3VA4112-6ED34-0AA0 - 125Amp Circuit Breaker

3VA4112-6ED34-0AA0  -  125Amp Circuit Breaker

When you’re dealing with electrical systems, reliability isn’t optional—it’s everything. The Siemens 3VA4112-6ED34-0AA0 circuit breaker is built to handle real-world demands, offering solid protection for commercial and industrial applications where failure simply isn’t an option. This 125 amp, 3-pole molded case circuit breaker is designed for line protection and delivers a strong 65kA interrupting capacity at 480V, giving you confidence in high fault conditions. It uses a thermal-magnetic (TM210) trip unit, which means you’re getting dependable overload protection along with a fixed short-circuit response set at 10 times the rated current. In plain terms—it reacts fast when it needs to, without overcomplicating things. Another advantage is its compact Frame 125 size. It fits neatly into panelboards and switchboards, making it a practical choice whether you’re working on a new install or replacing an existing breaker. And because it’s part of Siemens’ 3VA4 line, you’re getting a product that’s been engineered for consistency and long-term use.
