What matters for your BOM line is the breaking capacity curve: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. The thermal derating is published per 5 °C steps from 40 °C to 70 °C: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. If your panel ambient runs at 50 °C, you lose 60 A of headroom — plan the load accordingly. ## Footprint and panel integration The 138 mm width is standard for a 3-pole 630 A frame in the SENTRON 3VA2 series — it occupies the same mounting footprint as other 3VA2 breakers in this current class, so a panel laid out for a 3VA2 630 A frame accepts this unit without re-drilling the backplate. That gives you two form-C signals for status feedback and one dedicated alarm contact that changes state only on a trip event — useful for remote annunciation without wiring through the aux contacts.","metaTitle":"SENTRON 3VA2463-5JQ32-0AJ0 Molded Case Circuit Breaker, 630","metaDescription":"SENTRON 3VA2463-5JQ32-0AJ0 3-pole MCCB, 630 A rated current, ETU560 trip unit.
