What this module is
The ABB ACS180-04N-04A8-1 is a low-voltage AC machinery drive module — a panel-mount converter that sits between the feeder and a three-phase motor on a control cabinet sub-panel. The part description and title both classify it as an LV AC Machinery Drive Module, and it carries the ACS180 series identifier with an R0 frame size. Supply class is fixed at 200–240 V on a three-phase input, accepted across 47.5–63 Hz. That voltage window and frequency tolerance are the panel-side constraint the BOM line has to satisfy before this drive will start.
Frame, footprint and cabinet environment
Enclosure rating is Open Type / IP20, which is a cabinet-environment device — not a field-mounted unit. The panel builder is supplying the ingress protection, the EMC containment, and the thermal path; the drive itself expects a clean, closed enclosure.
As an LV AC machinery drive module in the ACS180 family, the part is intended for the standard role this class plays in machinery skids — feed a 3-phase induction or permanent-magnet motor from a 200–240 V supply, with the drive providing the speed/torque control and the motor-side protection that the upstream contactor and the downstream cabling rely on. Category placement under Servo Motor & Drives reflects that machinery-drive role rather than a generic VFD commodity line.
Sourcing and supply posture
For the panel builder, that means the unit is sized and specified first (R0 frame, 200–240 V, IP20), then sourced against the RFQ with the lead-time band feeding the project schedule rather than the other way around.
