What this order code is
The ACS800-U1-0030-5-D150: It sits in the U1 wall-mount drive class — the format that drops into a control cabinet beside the motor starter section rather than a through-panel or floor-standing build. Listed mass is 25.85 kg, which keeps it in the one-person-lift bracket but still dictates a panel-door check before the unit swings out on its hinge.
Why it ends up on a spares order
The U1 code is a known installed-base form factor: same drive, same control panel footprint, same terminal map across the family — which is why buyers chasing a line-down replacement quote against this exact MPN rather than a generic ACS800. ABB lineage (ASEA BROWN BOVERI on the nameplate string) keeps the part traceable against older documentation packs where the ASEA brand still appears on the bill of material.
Cabinet handling note
At 25.85 kg, plan for a two-handed lift with the chassis still on its back-plane mounting, and verify the cabinet hinge rating before the drive is swung out for service. Mounting style stays consistent with the ACS800-U1 series — same cut-out and keyhole pattern across the U1 frame, so a replacement drops into the existing bracket without rework.
Sourcing posture
Substitution questions are answered by quoting the exact code ACS800-U1-0030-5-D150 on its own.
