What this code actually is
The ABB ACS800-U1-0006-5-L502-L508-N660 is an ACS800-U1 series wall-mount AC drive, configured through the L502, L508 and N660 suffix options — the suffix tail is what distinguishes one variant from the next on the same frame, so when you cross it against a BOM line, match the entire string, not just the base ACS800-U1-0006-5 portion. It sits in ABB's Motor Drives class — a variable-frequency drive, not a soft starter and not a contactor — so the engineering decisions around it are sizing for motor kW/amps, DC-link braking on overhauling loads, and fieldbus option card placement rather than bypass contactor selection.
Handling on the panel
Chassis mass is 7.94 kgs, which is the threshold where a single tech can usually handle a wall-mount swap with a clear panel and a good shoulder, but it's heavy enough that a second pair of hands is the right call on a ladder or over a live bus — that's a handling decision, not a selection parameter, so it doesn't change the BOM choice.
Where the family sits now
ABB's current-generation successor to the ACS800-U1 platform is the ACS880-01 series — siblings like the ACS880-01-021A-5, ACS880-01-052A-5 and ACS880-01-07A6-5 all carry the same wall-mount footprint class under the Drives category, but ACS880-01 is a different control platform (different parameter structure, different firmware toolchain), so a swap is a re-commission, not a parameter file migration — confirm before quoting the cross.
Sourcing posture
The cleanest move on this code is to send the full suffix string in an RFQ and let the desk verify it against the available channel — quoting the base ACS800-U1-0006-5 alone risks the L502/L508/N660 options drifting on the PO, which is how BOM mismatches get built into a panel.
