The 3ABD00050537 is an ABB ACS380 machinery drive module in Frame R1, rated 4 kW normal-use output at 9.4 A on a 380-480 V three-phase supply. Heavy-duty use drops to 3 kW / 7.2 A; light-overload holds at 4 kW / 8.9 A. Frequency range covers 47.5 to 63 Hz, so it handles 50 Hz and 60 Hz mains without derating. Enclosure is IP20 — open type, intended for panel mounting where the cabinet provides the environmental seal.
The normal-use current (9.4 A) is the figure to match against your motor's full-load amps for continuous duty. Heavy-duty (7.2 A) governs applications with frequent starts or short overload cycles — if your load profile calls for 120% overload for 60 seconds, size against the heavy-duty column. Light-overload (8.9 A) splits the difference for modest transient demands. All three ratings assume the IP20 open-type enclosure is mounted in a clean, ventilated cabinet; derate if ambient exceeds 40 °C or if the panel is sealed.
