At 415 V it still holds 121 kA, and at 500 V it delivers 75.6 kA; at 690 V the rating drops to 9 kA, so for 690 V applications the breaker is suited only to lower-fault-current points in the network. No auxiliary switch is included; if you need remote status indication, that is a separate add-on. The breaker ships with the basic switch variant 3VA2463-5HN32-0AA0 as the supplied basic switch, so the order code already includes the switching mechanism; the UVR is integrated at the factory. ## Derating and thermal management The breaker derates linearly as cabinet temperature rises: 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 above 40 °C, use the derated value for the load — the 520 A floor at 70 °C is still a usable figure for a 500 A bus, but the 164.5 W maximum power loss must be ventilated out of the enclosure. The storage maximum is 10 °C above the operating maximum — that extra margin covers shipping and warehousing, not running conditions. Depth of 110 mm leaves clearance for rear-mounted busbars and cable lugs in a standard distribution panel.","metaTitle":"Siemens 3VA2463-5HN32-0BA0 3-pole MCCB, 630 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2463-5HN32-0BA0 molded case circuit breaker, 3-pole, 630 A rated, 187 kA breaking at 240 V.
