The Siemens SENTRON 3VA2463-7HL32-0CL0 is a 3-pole molded case circuit breaker (MCCB) rated for 630 A continuous current at 40 °C, with a derating curve that drops to 520 A at 70 °C — so if your panel ambient runs hot, size the load at the 70 °C figure, not the nameplate 630 A. Breaking capacity hits 330 kA at 240 V and stays at 242 kA through 440 V, then drops to 187 kA at 500 V and 9 kA at 690 V — the 690 V number is the weak leg; if your system runs at that voltage, verify the fault current doesn't exceed 9 kA or step up to a higher-rated frame. This is a line-protection design (not motor-protection), so it's intended for feeder and distribution duty, not direct motor starting — pair it with a contactor and overload for motor branch circuits.
Integration — fits and wiring
The basic switch is order code 3VA2463-7HL32-0AA0 — if you need the bare breaker without auxiliaries, that's the variant to source.
Thermal and environmental limits
Maximum power loss is 164.5 W — account for this heat in your enclosure ventilation calculation, especially when multiple breakers are ganged.
