The History Of Cutler Hammer


Cutler Hammer brand, by Schneider Electric, is an American manufacturer of electrical equipment headquartered in Palatine, Illinois. The company was founded on December 15, 1902 by Bryson Dexter Horton and James B. McCarthy. In the late 1800’s to early 1900’s Bryson Dexter Horton was credited with inventing the safety switch, and the first enclosed safety switch was introduced in 1909. Based in Detroit at the time, the company adopted the classic logo of the enclosed “D” for the city they were located in. In the early 1920’s Square D took advantage of the new-found concern for safety in the workplace, and began to promote their new line of safety switches for the growing number of factories throughout the country. Today Square D is an industry leader in the electrical world and was acquired by Schneider Electric in 1991. Schneider Electric also owns several other once-popular electrical brands such as Merlin Gerin and Telemecanique.


Leading the way for over 100 years, Square D is one of the most trusted and respected electrical brands in the world. They have helped companies innovate and re-create their marketplace in areas such as electrical utility, water and waste treatment plants, oil and gas industry, marine sectors and much more.
