What the order code is
The ABB ACS800-U1-0060-5+P901 is a wall-mount AC drive from the ACS800-U1 family carrying the +P901 option suffix, classified as a Motor Drive under Motors & Motor Controls. The ACS800-U1 platform is an ABB industrial drive line, the unit a retrofit buyer commonly meets on older panels that still have a working drive installed. Mass is 34.02 kg, which is in the bracket where two-person handling and panel-door swing have to be planned, not assumed.
Footprint class for cross-shopping
The ACS800-U1-0060-5+P901 and the ACS550-U1-072A-4+B055+L512 are both listed at 34.02 kg, the kind of match a controls integrator screens for when assessing a same-cabinet swap. The ACS880-01-065A-5 is an alternative in the same wall-mount drive class and is listed at 23.13 kg, so a swap to ACS880 is a weight decision before it is a wiring decision.
Integration and field-service notes
On a retrofit where the panel was originally specified around an ACS550, the ACS800-U1-0060-5+P901 keeps the same DIN-of-the-cabinet wall-mount form factor, but the control terminal map and the parameter tree are not the ACS550 set, so the commissioning engineer should plan to bring (or rebuild) the application macro rather than expect a direct parameter import.
