What it is and where it sits
The ABB ACS180-04N-03A3-4 is an LV AC machinery drive module out of the ACS180 line — module-mount format, frame R0, sized for 380–480 V three-phase input with a 0.98 power factor figure on the line. The I/O slice is fixed: 4 digital inputs and 2 digital outputs, 2 analog inputs and 1 analog output, with MODBUS as the listed communication protocol. IP20 open-type enclosure, rated to 2000 m altitude.
Environment and field-side fit
Open-type IP20 enclosure means the drive lives inside a cabinet — no dust or water exposure at the chassis. 2000 m altitude rating is the ceiling for installation without further derating; above that the thermal curve has to be revisited.
