The adjustable trip unit spans 945 A minimum to 5670 A maximum, so this breaker is set up as a main or heavy feeder device, not a branch-level component. Short-circuit interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and still holds 75.6 kA at 500 V; only at 690 V does it drop to 9 kA, which keeps it on the 480 V class switchboard side of the arc-flash boundary. Below 40 °C you get no upside — the rating is fixed at the 40 °C mark. Above 40 °C the derate is linear: 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, 520 A at 70 °C. If the enclosure ambient hits 50 °C, the breaker effectively becomes a 593 A device; don't load the bus to 630 A and expect the trip unit to hold. ## Environmental and auxiliary release details No undervoltage release is fitted on this variant. The trip indicator and voltage trigger are present, so the breaker can signal a trip condition externally without relying on the aux switch alone.","metaTitle":"Siemens 3VA2463-5HM32-0KJ0 SENTRON MCCB, 630 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2463-5HM32-0KJ0 molded case circuit breaker. 630 A at 40°C, 3-pole, 187 kA at 240 V, line protection.
