The ABB ACH580-01-073A-4+B056 is a 400V AC drive on the ACH580-01 series, catalogued under Motor Drives on the Motors & Motor Controls line. The +B056 option code is part of the order string as supplied, not a separate accessory. The drive's own series spine and voltage class place it squarely in the HVAC-style ACH580 family that ABB markets for pump, fan, and similar variable-torque loads. Listed weight is 9.07 kgs — large enough that one person handles the install but well inside a single-person lift envelope for a wall-mounted or panel-cabinet mount. No further electrical ratings (current, frame size, HP/kW) appear on the spec line; treat those as the datasheet's job, not the procurement record's.
Cross-shop within the ACH580 family
The closest same-function siblings on the same ACH580 family line are the ACH580-01-014A-4 at 6.80 kgs and the ACH580-01-023A-4 at 6.80 kgs, both lighter. A heavier frame variant, the ACH580-VCR-027A-4, is listed at 13.61 kgs. The 9.07 kgs figure on the 073A-4+B056 sits between those two, which is consistent with a mid-frame ACH580-01 build rather than the larger VCR chassis — relevant for a panel-builder weighing the swap against an existing cutout. None of these is a parametric replacement; they are different current frames in the same family.
