Drive module for 500 kW class motors
The normal-use current of 522 A is the figure to size cabling and upstream protection against. Heavy-duty use at 455 A gives headroom for constant-torque loads.
Frame R11 is a standard ABB drive module footprint. IP20 rated for panel installation with top and bottom gland-plate access. Open-type NEMA enclosure — no additional conduit box. Three-phase input, no neutral required. Efficiency IE2 meets the minimum for most EU motor-drive combinations; verify local regulations if IE3 or IE4 is mandated.
