The 3VA2463-6HL32-0CA0: The interrupting rating drops as line voltage rises: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. For most 400 V-class industrial panels the 187 kA rating gives substantial headroom above typical 50–65 kA SCCR requirements.
The 630 A rating holds only at 40 °C ambient inside the enclosure. Above that, continuous current must be reduced: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. If your panel ambient runs 50 °C, you lose roughly 6 % of the headline rating.
No auxiliary switch is included (specified as 'without'), so if you need status feedback, order the auxiliary switch block separately.
