What this code actually ships
The ABB ACS800-U4-0440-5+E210+P901 is the cabinet-built variant of the ACS800 family — the U4 designation meaning an integrated, floor-standing enclosure rather than the wall-mount modules the newer ACS880-01 line ships in.
Frame comparison — ACS800-U4 vs ACS880-01
The natural cross-shop candidate in the same ABB family is the ACS880-01-156A-5 at 55.00 kg — same vendor, same drive topology, but a wall-mount mechanical package roughly a quarter of the mass. Two further ABB cabinet-line peers sit further away from this frame — ACS550-U1-157A-4 at 89.81 kg (legacy ACS550 series, different control platform) and ACS880-01-065A-5 at 23.13 kg (smaller-frame wall-mount) — neither is a same-envelope swap.
