Rated In=630A with overload protection adjustable Ir=250A...630A and short-circuit protection Isd=1.5...9x Ir plus instantaneous Ii=9x In, it delivers Icu=55kA at 415V — breaking capacity class M. For a panel feeding a 630 A bus, that rating covers most industrial secondary-distribution fault levels. The ETU350 LSI trip unit gives you independent adjustment of long-time (Ir), short-time (Isd), and instantaneous (Ii) pickup, so you can coordinate selectively with downstream feeders. The adjustable neutral protection (OFF, 50%, 100%) is useful on 4-wire systems where neutral loading varies. ## Panel integration This is a 4-pole unit on the 3VA2 frame, designed for fixed mounting in a distribution panel or switchboard. The included nut keeper kit simplifies bus-bar connection during panel build.","metaTitle":"Siemens 3VA2463-5HN42-0AH0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HN42-0AH0 IEC frame 630 circuit breaker, 55kA breaking capacity @ 415V, ETU350 LSI protection, 630A rated.
