Duty ratings — normal vs heavy vs light overload
The 3ABD00048692-D: Three operating curves are defined: normal use at 37 kW / 73 A, heavy-duty at 30 kW / 61 A, and light-overload at 37 kW / 68 A. The heavy-duty figure governs sizing for applications that demand sustained torque below base speed — match the 61 A IhD to the motor FLA if the load profile is constant-torque. For variable-torque loads (fans, centrifugal pumps) the normal-use 73 A gives headroom. Light-overload at 68 A splits the difference for cyclic duty.
Mounting and enclosure details
Wall-mounted, IP21 with NEMA Type 1 enclosure. The R4 frame includes the gland plate and cooling duct clearance typical for this class. No separate cabinet is required for the drive itself in a clean indoor environment, but the WEEE Category 4 classification (any external dimension >50 cm) means end-of-life disposal routing should be planned at commissioning.
Efficiency class
Rated IE2 efficiency. For projects where IE3 or IE4 is mandated by local energy regulations, confirm the motor-drive system efficiency target — the drive itself meets IE2, which is the baseline for many industrial installations.
