Load Ratings and Duty Selection
The 3AXD50000146123: Three duty ratings are specified: normal-use (Pn 355 kW, In 503 A), heavy-duty (PhD 315 kW, IhD 460 A), and light-overload (PlD 355 kW, IlD 492 A). The heavy-duty figure governs continuous motor load for applications like conveyors or pumps where overload margin is needed; the normal-use rating suits variable-torque loads such as fans and centrifugal pumps. UL heavy-duty ratings are 400 Hp and 483 A.
