Drive module for high-power 3-phase applications
The ABB 3ABD00039443-D is an LV AC industrial single drive module rated for 315 kW normal use at 330 A, with heavy-duty output of 250 kW at 255 A and light-overload output of 315 kW at 320 A. It operates on a 3-phase supply at 525 to 690 V, 47.5 to 63 Hz, and carries an IE2 efficiency level. The module is IP20 protected and mounts in Frame Size R10.
The 330 A normal-use current (In) is the continuous rating for standard duty cycles — sized for a 315 kW motor on a 525-690 V line. The heavy-duty figure of 255 A (IhD) governs applications with higher overload demands, such as crushers or extruders. Light-overload rating (320 A, IlD) covers variable-torque loads like fans and pumps. The IE2 efficiency level means the module meets the IEC standard for premium efficiency.
