Frame size and fit in the panel
The 3ABD00048163: Frame R4 is the mechanical footprint. It mounts as a module — no separate base plate needed. The IP20 open-type enclosure suits cabinet installation where the surrounding gear provides the environmental seal. Keep the 47.5-63 Hz input frequency in mind if the supply is a variable-frequency genset or weak grid; the drive handles the full range without derating.
Duty ratings that matter for the BOM line
The normal-use 45 A output covers most constant-torque machinery drives up to 22 kW. Light-overload at 42.8 A sits between the two for applications with occasional short-duration peaks.
