The 3ABD00046935-D: The 37 kW normal-use power rating (Pn) matches the motor nameplate for constant-torque HVAC loads like fans and pumps. The 73 A normal-use current (In) is the continuous output the drive can deliver at rated conditions — size the input feeder and motor cable for this figure. Light-overload use is rated at 68 A (IlD), which gives a small headroom margin for occasional peak demand without upsizing the drive frame.
Rated for HVAC variable-torque applications — fans, pumps, compressors in commercial buildings and light industrial ventilation. The IE2 efficiency level meets current minimum efficiency standards for most markets, though some regions now require IE3 or IE4 for new installations; check local energy regulations if this is a new design rather than a like-for-like replacement.
