Breaking capacity runs 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 — figures that tell you this breaker is sized for high-fault utility feeds or large transformer secondaries where the available short-circuit current is substantial. ## Thermal derating — the real-world current you can actually run Above that, the breaker derates in 10 °C steps: 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 — common in a packed switchroom — you lose about 6 % of the nominal rating. Plan the load bus accordingly; the breaker won't trip on thermal overload at 593 A, but it also won't carry the full 630 A without nuisance tripping. ## What it does not carry — and why that matters for spec review The trip indicator is also absent, so there is no local mechanical flag showing the breaker tripped on fault versus manual off — something to note if your maintenance team relies on visual trip indication at the panel. ## Operating and storage range","metaTitle":"Siemens 3VA2463-5HN32-0CA0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5HN32-0CA0 molded case circuit breaker, 630 A rated current, 187 kA breaking at 240 V.
