The 73 A normal-use current (In) is the number that governs cable sizing and MCCB selection — not the light-overload 68.4 A (IlD). Both power ratings land at 37 kW because the drive's firmware clips output before the IGBT junction exceeds rating; in light-overload profiles the current limit is lower but the power ceiling stays the same. Frequency tolerance from 47.5 to 63 Hz means it accepts both 50 Hz and 60 Hz grids without derating, though the DC bus ripple at 50 Hz is slightly higher — expect a 5–8% higher ripple current in the bus caps at 50 Hz vs 60 Hz.

Frequently asked questions
What is the frame size of this drive?
Frame size R4. That determines the mounting footprint, heat sink dimensions, and the available option-slot configuration.
What compliance documentation is available for this drive?
The drive carries WEEE Category 5 classification. For RoHS, REACH, and UL documentation, the standard ABB declarations of conformity and compliance certificates are available upon request through the sourcing channel.
