What it is
The ABB ACH580-VDR-027A-6 is a member of the ACH580 VDR series, a wall-mount drive package in the 027A current frame sized for HVAC and general-purpose pump/fan duty in the ABB drives catalog. Listed weight is 23.00 kgs, so it is a two-handed panel-mount lift — bracket and fasteners should be confirmed for the cabinet's rated load before the drive is hung on the backplate.
Where this class is applied
ACH580 VDR-frame units cover the indoor, constant-torque and variable-torque loads typical of building-services and light-industrial panels — fans, pumps, and air-handling units where the drive sits in a dedicated MCC compartment or wall-mount enclosure. On a 027A frame the motor power point falls in the mid-range of the ACH580 line, which means cable runs to the motor should still be checked against the drive's reflected-wave limit; long pigtails beyond the published cable-length spec warrant a dV/dt or sine filter at the output terminals.
Comparison inside the same family
The closest same-family comparator is ACH580-PDR-027A-4+B056 at 16.33 kgs; the PDR frame and -4 supply-voltage suffix mark it as a different packaging and input-voltage variant rather than a drop-in replacement. The ACH550-UH-072A-4+B055 and ACH550-UH-078A-4 are listed at 24.04 kgs and sit in the prior ACH550 generation; they are not ACH580 units and are not a same-frame substitute.
Sourcing posture
The drive carries the ABB brand and is specified to order through independent industrial-automation channels — quote against an RFQ with the full suffix string (ACH580-VDR-027A-6) and any option codes so the supply side can confirm the exact build configuration before shipment.
