What the order code is
The ACH580-PDR-124A-4 is listed as a 124 A frame drive with 480 VAC three-phase input. The order code carries that frame and input class on its face, which is what the procurement line in the BOM keys off. At 162.84 kgs this is a heavy enclosure, not a wall-mount slab. That mass drives handling decisions — the cabinet needs a reinforced plinth, the lifting plan needs an overhead or floor cart rated for it, and the shipping crate is not a small-parcel box. Treat the figure as a handling/mounting rating, not a selection parameter.
Where the class is used
ACH580-series drives from ABB are general-purpose industrial drives specified for HVAC, pump and fan applications in 480 V three-phase distribution — the standard North American industrial feed. The 124 A frame places this unit in the higher-power band of that family, the size you see on a large chiller, a process water pump skid or a big exhaust fan rather than a small rooftop unit.
