Interrupting capacity hits 330 kA at 240 V and 242 kA at 415 V — that's extreme SCCR headroom for high-fault panels feeding motor control centers or transformer secondaries where a standard 65 kA breaker would cascade upstream. tr adjusts from 0.5 to 12 seconds, tsd from 0.05 to 0.5 s. ## Thermal derating — the real-world continuous current At 50 °C it's 570 A, at 60 °C it's 510 A, at 70 °C it's 450 A. That's the heat you need to vent through the enclosure; factor it into your thermal budget if the panel is sealed or outdoor-rated. That's a 3-pole frame in the SENTRON 3VA2 family — the same footprint as other 630 A 3VA2 variants, so a panel laid out for a 3VA2 630 A will accept this unit without re-drilling. Mounting is standard for the class: screw-fixed to a backplate or DIN-rail adapter. The 110 mm depth leaves room for rear-connected busbars or cable lugs in a typical 600 mm deep enclosure.","metaTitle":"Siemens 3VA2463-7JQ32-0AA0 SENTRON MCCB, 630 A, 3-Pole, ETU5","metaDescription":"Siemens 3VA2463-7JQ32-0AA0 SENTRON molded case circuit breaker, 630 A at 40 °C, 3-pole, ETU560 electronic trip unit, 330 kA at 240 V.
