3VA4140-6ED34-0AA0 - 40Amp Circuit Breaker

3VA4140-6ED34-0AA0  -  40Amp Circuit Breaker

When you’re protecting critical electrical systems, you don’t want guesswork—you want proven performance. The Siemens 3VA4140-6ED34-0AA0 SENTRON molded case circuit breaker is built for exactly that. Designed for commercial and industrial power distribution, this 40 amp, 3-pole breaker delivers dependable protection against overloads and short circuits, even in high-demand environments. What really sets this breaker apart is its 65kA interrupting capacity at 480V, giving you the confidence to handle high fault conditions without compromising safety. Paired with a thermal-magnetic TM210 trip unit, it reacts quickly and consistently—helping prevent damage to equipment, costly downtime, and unnecessary risk. If you’re running HVAC systems, control panels, or heavy-duty machinery, this breaker quietly does the job it’s supposed to do: protect everything downstream. And because it’s part of Siemens’ trusted SENTRON 3VA4 series, you’re getting a compact, field-proven solution that’s easy to integrate into existing setups without overcomplicating installation.
