Duty ratings & enclosure
The 3ABD50000038965: Three overload curves are defined: normal-use (Pn 1.1 kW, In 3.3 A), heavy-duty (PhD 0.75 kW, IhD 2.6 A), and light-overload (PlD 1.1 kW, IlD 3.1 A). The heavy-duty figure governs continuous operation on a constant-torque load like a conveyor or positive-displacement pump; the normal-use figure applies to variable-torque loads such as centrifugal fans and pumps. IE2 efficiency class meets the minimum for most European and Asian markets.
