What you're sourcing
The ABB ACS800-04-0025-7+P901 is a wall-mount AC drive in the ACS800-04 family, carrying the +P901 option suffix and catalogued under Motors & Motor Controls / Drives / Motor Drives. The series code on the nameplate is the string a buyer will quote on the PO and trace against the packing list — nothing else in this class reads the same way. The drive's listed shipping mass is 11.73 kgs, which puts it in the one-person-handle bracket for bench work but still worth a panel-side structural check on a swing-mount plate or in a tall enclosure where the centre of gravity sits high. ABB is the brand of record for the order code; that is what governs manual retrieval, parameter file compatibility, and which firmware generation the commissioning tool will accept. Documents and firmware should be requested against this string and not against a generic ACS800 code.
ACS880 generation — the cross-shop question
Treat the ACS880-01 candidates as same-class, not drop-in. A panel that was specified and wired around an ACS880-01-034A-5 will not accept an ACS800-04-0025-7+P901 without re-landing the control terminals and re-mapping the parameter file; the reverse is also true. Use the generation delta to choose — keep the line on ACS800, or commit to a planned migration to ACS880 with the wiring and firmware work that implies.
Application-fit notes
ACS800-04 wall-mount frames are sized for industrial motor control in the low-voltage class, with the DTC control scheme that ABB documented for this series. Buyers fitting one to a load should still verify output filter requirements against the motor cable length on site — reflected-wave dV/dt on long motor cables is the usual premature-winding failure mode for this family, and a dV/dt or sine filter at the drive output is cheaper than a rewind.
