Configuration notes from the suffix codes
The ACS800-31-0060-3+E200+K451: The order string ends +E200+K451, which means the converter ships with two option packages already integrated — not as field-installed kits. For a sourcing buyer that matters because the BOM line is complete as written: a +E200 or +K451 option added later as a separate part is not the same configuration, and the panel-builder commissioning notes that travel with the cabinet assume both codes are present from the factory.
Sourcing posture
This catalog line is specified into the BOM by full order code and quoted to order against an RFQ — the +E200 and +K451 suffixes travel with the unit, so a like-for-like requisition needs the exact string, not a base ACS800-31-0060-3 with options added later. Reach out with the full MPN and the panel context (cabinet, motor rating, fieldbus) and the quote comes back against the same configuration the line was frozen on.
