The Siemens 3VA1463-4EF32-0AA0-ZD00 is a 3-pole IEC frame 630 circuit breaker with a 36kA interrupting capacity at 415V — class S breaking capacity, meaning it handles high-fault scenarios typical in industrial distribution panels without cascading upstream. The TM240 ATAM thermal-magnetic trip unit gives you adjustable overload protection from 440A to 630A (Ir) and short-circuit pickup from 4 to 8 times In. That 4:1 overload adjustment range is what lets you fine-tune coordination downstream without swapping the breaker body.
The base breaker body and trip unit are standard 3VA1 platform parts, so the mechanical footprint and termination match the wider 3VA family. Panel builders: the 3VA1 frame accepts the same accessories (auxiliary switches, shunt trips, rotary handles) as the standard catalog, just watch the ZD00-specific kit if you're swapping into an existing build.
