What the order code is
The ABB ACH580-VDR-052A-6 is an ACH580-series motor drive in the wall-mount VDR frame, listed under Drives / Motor Drives inside the ABB ACH580 product line (ASEA BROWN BOVERI).
Handling and panel fit
Listed at 53.07 kgs, this drive is a two-person lift or hoist job onto a panel backplate — not a shelf unit, and not something a wireman slides into a DIN bay by hand. On a hot-strip mill floor, that mass also means the cabinet has to be specced for the weight; mounting surface and panel reinforcement matter before the drive goes in next to other megawatt-class equipment.
Series context and second-source question
The older ACH550 generation — ACH550-UH-097A-4 at 33.57 kgs and ACH550-VDR-059A-4 at 31.75 kgs — is a generation behind and a different mechanical frame; useful only as a last-resort spare against an ACH580 line, not as a like-for-like alternate.
