The 3ABD00039368-D: The normal-use rating (400 kW, 725 A) covers constant-torque applications like pumps and fans at full speed. The heavy-duty rating (315 kW, 566 A) is the figure to size for high starting torque or cyclic overloads — conveyors, crushers, extruders. The light-overload rating (400 kW, 715 A) sits close to normal use and suits variable-torque loads with occasional peak demand. Matching the duty class to your motor's starting profile avoids oversizing or nuisance trips.
Frame R11 requires dedicated cabinet space and a gland plate for incoming power cables. IP20 rating means enclosure mounting; no additional sealing needed inside a clean panel.
