The ABB 3ABD00046938-D is an ACH531-01 wall-mounted HVAC drive rated 75 kW normal use at 145 A, with a light-overload rating of 75 kW at 138 A. It runs on 380-480 V three-phase input, frequency range 47.5-63 Hz, and carries IE2 efficiency. Frame size R6, IP20 enclosure, NEMA Open Type.
Key Ratings & Fit
The normal-use current of 145 A (75 kW) is the figure to size branch protection and cabling against. Light-overload use allows 138 A continuous — useful for constant-torque HVAC loads like fans and pumps that rarely hit peak. The 380-480 V input covers common global low-voltage mains; the 47.5-63 Hz frequency tolerance handles weak grids or gen-set supply.
Integration Notes
Wall-mounted, IP20 — install in a clean, dry enclosure. Frame size R6 determines the mounting footprint and gland-plate dimensions; verify panel cut-out against the installation manual before drilling. The IE2 efficiency class meets current minimum standards for most HVAC applications.
