Littelfuse LS6R04004DD00L versus ABB OTDC320UFSV02:
PDF page 1, row 11. Printed row: OTDC320UFSV02 | 27PV3026 + 27091041* | OTDC400UFSV02 | LS6R04004DD00L 1500 V dc 400 A 1P 4D Grounded 27PV3032 + 27091041* | OTDC320UFSV11 | 27PV3039 + 27091041* (x2) | OTDC400UFSV11. 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.
