It sits in the Motor Drives category under Drives and Motors & Motor Controls, so a buyer landing on this code is sourcing a low-voltage general-purpose drive, not a servo or a soft starter — the BOM line should be coded to match. The drive lists 18.14 kg, which is the weight the panel builder has to plan around for the cabinet shelf or backplate — a hoist or two-person lift, not a tabletop swap, and not a number that drives the electrical selection. ## What the +L512 suffix means at the order-code level On the ACS550 U1 platform the suffix after the base code is the option set shipped from the factory, and +L512 is part of that build — so the BOM line must carry the full string, not the base code alone. The category trail (Motors & Motor Controls > Drives > Motor Drives) is the line a controls integrator files the drive under, and it is the line the option suffix travels with into the cabinet. ## Where the option string lands in a controls build The ACS550 U1-frame AC drive carries the +L512 option suffix in the order code; integrators read the full suffix string to match the drive to the motor and the panel layout. At 18.14 kg the unit is in the lift-with-help bracket — plan the backplate, the door swing, and the cable bend radius around that mass, then size the motor cable run to the drive's own cable-length and EMC limits.","metaTitle":"ABB ACS550-U1-038A-4+L512 AC Drive, 18.14 kg","metaDescription":"ABB ACS550-U1-038A-4+L512 AC drive, ACS550 U1 frame, +L512 option suffix, listed at 18.14 kg.
