The electrical engineering company DRIESCHER is a traditional and at the same time innovative medium-sized group of companies in the field of energy and railroad technology with worldwide sales markets and approx. 500 employees with locations in Moosburg and Eisleben as well as in the Czech Republic. DRIESCHER is the system provider for the development and production of application-specific, durable and clean switching devices and systems for the intelligent control of energy flows.
DRIESCHER products play an important role in the energy transition by advancing energy distribution in low- and medium-voltage networks and preparing the power grids for the future.
At the beginning of the last century, Fritz Driescher Sr. (*1886; †1951) recognized the importance that power supply would have in the years to come. In 1909, aged just 24, he founded his company in Kapellen on the Lower Rhine, laying the foundations for the success story of the DRIESCHER companies that continues to this day.
In the early years, the focus was on the electrification of wells, centrifuges, chopping machines and lathes. Just one year after the company was founded, it employed 30 electricians. In 1925, the company moved to larger premises in Rheydt. In 1939, a large branch factory was opened in Moosburg/Upper Bavaria, which became the property of Fritz Driescher jun. in 1948 (today DRIESCHER Moosburg). In 1951, the youngest son of Fritz DRIESCHER senior, Heinz Driescher, took over the company in Rheydt and decided to relocate and build a new plant in Wegberg (today DRIESCHER Wegberg) at the end of the 1950s.
Ever since Fritz Driescher founded the company, research and development has been an essential part of our corporate culture.
