The 630 A rating holds only at 40 °C ambient. Above that, the continuous current must be derated: 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. The maximum power loss is 162 W, so the enclosure ventilation needs to handle that dissipation at the chosen derated current. ## Panel integration — footprint and protection class That depth (110 mm) is the dimension from the mounting surface to the front cover — critical for enclosure depth planning, especially if the panel has a shallow gland plate or a rear-mounted busbar system. ## Ground-fault and communication — what the ETU860 adds Communication function is present (yes), which means this breaker can report status and trip events over a bus system, though the exact protocol is not listed in this spec set. The undervoltage release is not fitted on this variant; if undervoltage protection is required, a different order code or an add-on module is needed.","metaTitle":"Siemens 3VA2463-0KQ32-0AA0 SENTRON MCCB, 630 A, 440 kA at 41","metaDescription":"Siemens 3VA2463-0KQ32-0AA0 SENTRON molded case circuit breaker, 630 A continuous, 440 kA breaking at 415 V.
