What the order code is buying
The ABB ACS880-07-1250A-3 is a cabinet-format industrial motor drive from the ACS880-07 family, specified for 50 / 60 (+/- 5%) Hz supply and weighing 802.86 kgs as a complete cabinet assembly. The -07 suffix means this is a cabinet-built drive with line filter, switching, and I/O integrated into an enclosure; it is specified as a single line item, not a chassis that the panel builder mounts to a sub-panel.
What the 50 / 60 Hz (±5%) figure governs
The 50 / 60 Hz with ±5% tolerance is the input frequency spec carried on this listing, and it is the figure that decides whether a weak-grid or genset-fed site can run the drive without an upstream conditioner. No motor-side current, voltage class, or overload rating is captured in this record, so frame sizing, cable selection, and braking-resistor choice have to be confirmed against the drive's full data sheet before this order code is signed off against a specific motor load.
Sourcing posture for the line
ABB is the brand for the ACS880-07-1250A-3, and the line is specified to order against an RFQ with the BOM line and motor-load details confirmed against the full data sheet before release.
