For a 630 A frame, the 187 kA at 240 V is high enough for most secondary-side distribution; the 121 kA at 415 V covers heavy industrial mains. Thermal derating is built into the spec: 630 A at 40 °C drops to 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. Maximum power loss is 164.5 W — factor that into enclosure ventilation. There is no auxiliary contact version, no ground fault monitoring, no phase failure detection, and no voltage trigger. The supplied basic switch is 3VA2463-5KP32-0AA0.","metaTitle":"Siemens 3VA2463-5KP32-0BA0 SENTRON MCCB, 630 A, 3-pole, line","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0BA0 molded case circuit breaker, 630 A rated at 40 °C, 3-pole, ETU850 release, 187 kA at 240 V.
