Siemens AG is a German engineering conglomerate, the largest of its kind in Europe. The company has three main business sectors: Industry, Energy, and Healthcare; with a total of 15 divisions. Siemens manufactures circuit breakers, motor controls and other electrical distribution products. They have an installed base of Motor Control Centers dating back to 1964 due to acquisitions of Allis-Chalmers in 1978, ITE Gould in 1983 and Furnas Electric in 1996. This has resulted in eleven MCC models installed across the United States.
