3VA4150-4ED34-0AA0 - 50Amp Circuit Breaker Description
3VA4150-4ED34-0AA0 - 50Amp Circuit Breaker
When you're choosing a circuit breaker, you're really choosing how much risk you're willing to tolerate. The Siemens 3VA4150-4ED34-0AA0 is built for people who don’t want to take chances. It’s a 50-amp, 3-pole molded case circuit breaker designed to quietly do its job—protect your system from overloads and short circuits—without needing constant attention. This model comes with a fixed thermal-magnetic trip unit (TM210), which means the protection settings are already dialed in. No adjustments, no second-guessing. It trips when it should, and stays out of the way when it shouldn’t. With an interrupting capacity of 25 kA at 480V (and up to 65 kA at 240V), it’s well-suited for commercial and light industrial environments where reliability matters more than bells and whistles. It’s also part of Siemens’ SENTRON 3VA4 line, so you’re getting a design that’s widely used, well-supported, and trusted across a range of applications—from HVAC systems to distribution panels. Install it once, and you can move on to more important things.
