What the code points to
The ACS800-ITTU1-0006-5+P901: The plus-suffix '+P901' is stamped into the order code on this build, so a quote, RFQ, or replacement request should carry that suffix verbatim — dropping the '+P901' lands on a different configured unit. Listed mass is 6.80 kgs for the drive as catalogued — a one-person lift but worth checking against the cabinet weight budget before the slot is committed.
Where this class of unit sits on the line
ACS800-series units are the ABB industrial-drive family used to run three-phase induction and PM motors from a panel-side converter, so the ACS800-ITTU1-0006-5+P901 inherits that motor-control role on the line it gets bolted into. The IT (industrial) enclosure form factor with the '+P901' option build is the variant typically specified where the panel designer wanted the standard ACS800 control interface plus the P901 option package rather than a base-only configuration.
Sourcing posture
Compliance documentation (RoHS, REACH, UL, IEC) is not on the face of this catalog entry, so request the declaration pack through the RFQ channel rather than assuming a specific approval set.
