Its headline rating is 630 A continuous current at 40 °C ambient, with an interrupting capacity of 242 kA at 240 V and 187 kA at 415 V — numbers that tell you this breaker is sized for high-fault industrial feeders, not light branch circuits. The 630 A rating is the rated continuous current Iu at 40 °C, but the thermal derating curve is published: at 50 °C it carries 593 A, at 60 °C it carries 557 A, and at 70 °C it carries 520 A.
Panel integration and auxiliary wiring
The 3VA2463-6HL32-0DC0 measures 138 mm wide by 248 mm high by 110 mm deep — a standard MCCB footprint for 630 A frames. No communication function, no phase failure detection, no ground fault monitoring — this is a straightforward line-protection breaker, not a power monitor. Maximum power loss is 164.5 W — that heat must be vented or accounted for in the enclosure thermal budget.
