History
SEL was founded in Pullman, Washington in 1982 when Dr. Edmund O. Schweitzer III invented and marketed the first all-digital protective relay. Schweitzer's invention revolutionized the industry by reducing the size, cost, and complexity of protective relays while adding communications and reporting capabilities.
Schweitzer created the relay as a Ph.D. project while at Washington State University. He sold his first product, the SEL-21, to Otter Tail Power Company in Fergus Falls, Minnesota in 1984. Otter Tail initially used the SEL-21 for its fault location and event recording functions.
In 1985, SEL built its first building and employed eleven people. In 2009, SEL became 100% employee-owned under an employee stock ownership plan (ESOP).
SEL has four manufacturing facilities in the U.S. located in Pullman, Washington; Lewiston, Idaho; and Lake Zurich, Illinois. In 2003, the company opened its first Regional Integration Center in San Luis Potosi, followed by May 2017 opening in Saudi Arabia city of Dammam with a peak manufacturing ablitiy for 1,200 control panels. With Mexico to build complete panels and PowerMAX for all of North America. The components for the panels are made in Pullman and shipped to Mexico where they are integrated into panels.
E. O. Schweitzer Manufacturing, a manufacturer of fault indicators and sensors started by Edmund O. Schweitzer, Jr. in 1949, became a division of SEL in 2005.
