What the line card says
The ACS880-01-361A-5+K492: On the bench, this one announces itself by mass before anything else. The listed weight is 97.98 kg, which puts it in two-person-lift territory and means the cabinet plinth and any swing-arm provision have to be sized for a heavy drive module rather than a small inverter. That weight, more than the catalogue headline, drives the receiving and installation plan.
Read the option code before you mount it
The +K492 suffix on ACS880-01-361A-5+K492 is a factory-installed option build on top of the base 361 A frame, not a separate part number. Because the option layer is bolted in at order entry, the control board layout, terminal map and any auxiliary I/O depend on which +K4xx codes were selected, so the build sheet travels with the nameplate — pull that off the cabinet door before you start wiring and reconcile it to the PO line.
Same family, different frame
ACS880-01-156A-5 weighs 55.00 kg, ACS880-01-065A-5 weighs 23.13 kg and ACS880-01-040A-5 weighs 18.14 kg. The seed unit at 97.98 kg is the heaviest of the set, and none of the three peers is a like-for-like swap because the mass and frame change together.
What the controls integrator and the wireman need to plan
Plan the cabinet around 97.98 kg of drive mass plus the cable bend radii on a 3-phase 380-500 V input, and reconcile the +K492 option build on the build sheet against the PO before termination. The family placement under Motor Drives is a taxonomy cue, not a rating — the input voltage range and the frame are the numbers that decide the panel cut, the gland plate sizing and the lifting plan.
