3VA4111-4ED34-0AA0 - 110Amp Circuit Breaker

Siemens 3VA4111-4ED34-0AA0 Circuit Breaker – 110A, 3-Pole, 25kA @ 480V

If you’re looking for a dependable solution to protect your electrical system without overcomplicating the install, the Siemens 3VA4111-4ED34-0AA0 circuit breaker checks all the right boxes. Built on Siemens’ trusted 3VA4 platform, this 110 amp, 3-pole molded case circuit breaker is designed to handle real-world demands—whether you're managing a commercial facility, upgrading a panel, or maintaining industrial equipment.

What makes this breaker stand out is its balance of simplicity and performance. With a 25 kA interrupting rating at 480V, it’s ready to respond when it matters most—cutting off dangerous fault currents before they can damage your system. The thermal-magnetic (TM210) trip unit gives you reliable, no-nonsense protection: a fixed 110A overload setting paired with an instantaneous trip at 10x the rated current for fast short-circuit response.

In plain terms? It does exactly what you need it to do—protect your equipment, reduce downtime, and keep your operation running smoothly.
