Socomec starred cells require jumpers; no composite assembly is reduced to a bare switch. The source lists multiple 320/400-series ABB and/or Socomec codes against a 400 A Littelfuse row; ratings must be checked individually. Historical manufacturer-listed selection candidate, not a drop-in guarantee. Verify current ordering codes, ratings, circuit function, poles/wires, enclosure, mounting, approvals and application suitability. Bidirectional discovery does not imply symmetric technical interchangeability. No transitive cross is inferred.
Counts describe recorded relationships, not stock, sales, testing or independent qualification. Manufacturer-and-part identities remain separate. Indexing dates do not establish current specifications or availability.
Check current manufacturer documents and electrical, mechanical, environmental and application requirements before selecting a replacement.
