That 630 A figure is the thermal baseline — the breaker is designed to carry that load continuously without tripping, making it a fit for main feeders or large sub-feeders in industrial distribution. The interrupting ratings climb to 187 kA at 240 V and 121 kA at 415 V and 440 V, then drop to 75.6 kA at 500 V and 9 kA at 690 V. The thermal derating curve is published: 630 A at 40 °C, stepping down to 450 A at 70 °C. That means if your enclosure runs hot, you lose nearly a third of the ampacity — plan the ventilation or upsize the frame.
No auxiliary switch or ground-fault monitoring module is fitted as-delivered; those are add-on options if the application requires them. The basic switch variant is 3VA2463-5KP32-0AA0 — same frame, no UVR or comms.
