3VA4190-4ED34-0AA0 - 90Amp Circuit Breaker

3VA4190-4ED34-0AA0  -  90Amp Circuit Breaker

If you’re sourcing a reliable 90 amp circuit breaker for a commercial or industrial setup, the Siemens 3VA4190-4ED34-0AA0 is a straightforward, no-nonsense option that gets the job done. It’s part of Siemens’ SENTRON 3VA4 line, built for consistent protection where equipment downtime isn’t something you can afford. This is a 3-pole molded case circuit breaker with a 25 kA interrupting rating at 480V, so it’s well-suited for handling higher fault levels in typical three-phase systems. The thermal-magnetic trip unit (TM210) is factory set, which means you’re not spending time dialing things in—what you get is predictable overload and short-circuit protection right out of the box. It’s also compact, easy to fit into most panel layouts, and designed to hold up over time. Whether you’re replacing an existing breaker or building out a new panel, this one keeps things simple and dependable—which is usually exactly what you want.
