Headline ratings and what they mean for your panel
The Siemens 3VA4140-6ED14-3AA0 is a 1-pole circuit breaker in the 3VA4 UL Frame 125 family, rated 40 A continuous with a 65 kA interrupting capacity at 277 V. That 65 kA SCCR at 277 V means it can safely clear a bolted fault up to that level without cascading upstream — critical for maintaining selectivity in a panel where downstream breakers are coordinated. The TM210 trip unit provides fixed thermal-magnetic overload protection: Ir is permanently set at 40 A, and the short-circuit pickup Ii is fixed at 10 × In (400 A). No adjustment range means no mis-set trip during commissioning.
