It is designed for busbar connection via front terminals, typical for main incoming or load-switching duties in distribution panels where isolation, not protection, is the requirement.
The 630 A rating holds flat from 40 °C through 50 °C, then derates to 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C. The 15 000 typical mechanical operating cycles give a solid service life for a disconnect that sees daily switching, not just emergency isolation.
The 3VA1463-1AA32-0AA0 measures 138 mm wide, 248 mm high, and 110 mm deep — a compact footprint for a 630 A disconnect. The front terminal arrangement and busbar connection mean it bolts directly onto a busbar system, not wired through lugs. IP40 on the front protects against tools and solid objects larger than 1 mm; the rest of the device is open to the enclosure interior, so the panel itself must provide the overall IP rating. The design accepts an optional motor drive for remote switching, and the mechanical service life of 15 000 cycles supports automated or frequent operation.
