The 630 A frame is the largest in the 3VA2 family, sized for main feeders or large motor branch circuits in industrial switchboards. Breaking capacity is 440 kA at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — these figures tell you the breaker can safely interrupt fault currents up to those levels without cascading upstream. For a 480 V panel (common in North America), the 330 kA at 440 V rating is the closest reference; at 600 V class, the 220 kA at 500 V applies. The 690 V rating of 52.5 kA covers European 400/690 V systems. The ETU850 electronic trip unit supports communication, enabling integration with energy management or SCADA systems for remote monitoring and selective coordination. ## Temperature derating — don't size by the 40 °C number alone At 45 °C it derates to 600 A, at 50 °C to 570 A, at 55 °C to 540 A, at 60 °C to 510 A, at 65 °C to 480 A, and at 70 °C to 450 A (–). ## Mounting and integration — fits standard panel cutouts The 3-pole frame mounts via four screws to a backplate or DIN-rail adapter (not included). Front IP40 protection means it's suitable for enclosed distribution boards but not washdown environments.","metaTitle":"Siemens 3VA2463-8KP32-0AA0 SENTRON MCCB, 630 A, ETU850, 440","metaDescription":"Siemens 3VA2463-8KP32-0AA0 SENTRON molded case circuit breaker, 630 A continuous, ETU850 electronic trip, 440 kA at 240 V.
