Square D- SCHNEIDER Electric Schneider sub-brand

From residential to industrial buildings, one of the most trusted brands in power distribution, power and control.

In 2003, the Schneider Electric brand Square D celebrated its 100th anniversary. 100 years of expertise and innovation in power and automation management.

1902: The Detroit Fuse Manufacturing Company is formed, which manufactures fuses in boxes and fuse switches in boxes.

The name Square D was chosen because of the company's reputation for having a "D" logo on its catheter case. In the 1940s, Square D had 10 factories in the United States, employing 7,000 people and making half of the circuit breakers used in aviation.

In the 1950s, the company opened its first European subsidiary. It also has subsidiaries in Asia and South Africa. The brand introduced programmable robots, a new generation of home boxes, fire detectors to prevent current overcharging and detect/interrupt arcing.

In 1991, Schneider Electric acquired Square D.

The Schneider Electric brand Square D develops products and systems in a wide range of industries, from circuit breakers to monitoring systems. The tertiary and residential construction industries are the main consumers of Schneider's electric product Square D.
