Square D Company History
The name Square D originated from one of the company's first products, a new safety switch with the company's new logo, a "D" (for Detroit) inside a square. The product quickly became the industry standard and many customers began asking for "those square D switches." The trademark was developed in 1915, and the name Square D Company was formally adopted in 1917. To this day, Square D is one of the few companies ever named by its customers.

On May 24, 1991, Square D Company merged with Schneider Electric of Paris, France. Schneider Electric is the world's leading manufacturer of electrical distribution and industrial control and automation products and systems, and the only manufacturer dedicated solely to the distribution and control of electricity.
