Drive selection for a 55 kW HVAC fan or pump
The ABB 3ABD00046366 is an ACH531-01-106A-4 LV AC wall-mounted drive built for HVAC duty. It delivers 55 kW at 106 A on a 380–480 V three-phase supply, with a light-overload rating of 100 A at the same 55 kW output. Frame size R5 keeps the footprint manageable for panel layouts where space is tight.
The 106 A normal-use current matches a 55 kW motor at full load; the light-overload curve holds 100 A continuously, so it handles fan or pump starts without derating. Standby loss of 24 W is low enough that ventilation requirements stay modest — no forced cooling needed in a typical IP20 enclosure. The 47.5–63 Hz input range covers 50 Hz and 60 Hz grids globally, and the IE2 efficiency level meets the minimum for most HVAC specs in regions that mandate it.
Wall-mounted in an IP20 cabinet, the R5 frame accepts standard DIN-rail or backplate fixing. The 380–480 V three-phase input lands on the power terminals; control wiring runs to the I/O connector. Ambient temperature must stay at or below 40 °C for full rated output — derate above that per the drive's thermal curve.
