We speculate that these assemblies were intended for use in a 480VAC 500kW wind power converter, possibly using multiple units in a 3PH delta configuration, but were're not certain. We have specification sheets for the components, but not the full assemblies. See detailed photos showing all components. Units weigh 92 lbs, dimensions are approximately 28 x 9.5 x 14 inches. We recommend shipping by freight carrier (please inquire).
