What it is and where it lands
The ABB ACS380-040C-12A6-4+K492 is a machinery drive in the ACS380 family, specified for a 3-phase 380–480 V supply and intended for motor control in equipment-builder panels. It carries the +K492 option suffix, which is the order code to specify when quoting the BOM line — not the bare frame string. The 12A6 current class in the order string is the rating that drives breaker and cable sizing downstream, so the panel single-line should be cross-checked against that figure before the drive is locked into the slot.
Handling and panel fit
Mass on the nameplate is 1.81 kgs, which is the figure to use for cabinet bracing and for the lift plan when the drive is being swapped on a line that is already live. It is a wall-mount / cabinet-mount package rather than a through-panel unit, so clearance around the heat-sink profile governs the layout, not the kilogram figure alone.
Sourcing posture
No lifecycle entry is in the ledger for this MPN, so the BOM line should be quoted to order against an RFQ rather than assumed off-the-shelf.
