That means you get both remote status and a dedicated fault signal without adding external relays. Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V — the 240 V figure tells you this breaker handles high-fault upstream feeds comfortably; the 690 V number is the weak link if you're on a 690 V system, so verify your available fault current. That depth is tight for shallow enclosures; measure your backpanel clearance before committing the BOM. If you need ground-fault or comms, you step up to the 3VA2 with those options. ## Thermal derating curve Rated 630 A at 40 °C ambient, 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 enclosure ambient sits at 50 °C, you lose roughly 6 % of the headline rating — plan your load accordingly. That heat has to leave the enclosure; factor it into your ventilation or cooling budget.","metaTitle":"Siemens 3VA2463-5HL32-0KL0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens 3VA2463-5HL32-0KL0 SENTRON molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, 187 kA at 240 V.
