What the BOM line is buying
The ABB ACS180-04N-050A-4 is an LV AC machinery drive module — a low-voltage variable-frequency drive intended for cabinet-mount control of standard industrial motors. It takes a 3-phase supply between 380 V and 480 V at 47.5... 63 Hz, which fixes the upstream transformer or feeder spec the panel builder has to coordinate with. Enclosure is Open Type / IP20, meaning the drive belongs inside an enclosure — not on the machine surface — and clearances around the housing are part of the panel layout, not an afterthought.
Mechanical envelope and cabinet planning
The R4 frame measures 10.236 in wide by 9.449 in high by 7.031 in deep, so cabinet cutout, door swing, and adjacent component spacing all key off that footprint. Module mounting type is the standard ABB module pattern for this frame, sized to drop into a panel build without adapter plates. At a 2000 m altitude rating, no site de-rating applies for most industrial plants; any installation above that ceiling needs a thermal review against the drive's own derating curve.
Line-side and acoustic notes
Power factor lands at 0.98, which is the figure a site electrical engineer cites when sizing the feeder, the PFC bank, and the harmonic study — that number is the line-side posture, not the motor-side output. Sound emission is 69 dB(A), so cabinet acoustic treatment only matters if the enclosure sits in an operator-occupied zone; in a plant-room or remote MCC the level is unremarkable.
Shipping and compliance posture
The unit ships without any battery or cell fitted, which keeps the dangerous-goods profile flat for airfreight and standard sea-freight declarations. Estimated lead time of 1 - 10 working days frames the procurement posture: this is a drive that gets quoted to order against an RFQ rather than pulled off a shelf, so lock the BOM line early if a slot is needed inside that window.
