Jean Müller Elektrotechnische Fabrik

Jean Müller GmbH Elektrotechnische Fabrik is a German manufacturer of fuse-based switching devices and low-voltage power distribution equipment, serving industry, energy utilities, and switchgear and controlgear builders. The company was founded in 1897 in Eltville am Rhein by Johann Baptist Müller, known as Jean, and has kept its headquarters in that Rhine town ever since. It employs roughly 600 people and operates through subsidiaries in Austria, China, Poland, Switzerland, and Singapore, making it an internationally active mid-sized German industrial firm. The business began with the installation of electrical systems, but Jean Müller quickly recognised the importance of protecting cables and equipment against short circuits and overloads. He started producing fuse strips and fuses based on the Siemens/Schuckert patent of 1901 and continued to develop that technology. Fuse technology remains the foundation of the company's business today, and the product portfolio has been expanded over the decades with fuse bases, accessories, fuse-based switching devices, and matching enclosures. Jean Müller's best-known products are house connection boxes for the basements of private homes and distribution cabinets for energy utilities. Its wider range covers fuse links — mainly NH, semiconductor protection, and HH fuse links — power distribution components such as switch-disconnectors with fuses, fuse rails, and busbar systems, energy distribution equipment such as house connection technology, distribution and equipment cabinets, and low-voltage switchboards, as well as system electronics including measured-data acquisition systems, electronic monitoring devices, and software. The company survived the Second World War without major war damage between 1939 and 1945; in 1946 it employed 100 people producing fuses, with revenue equivalent to 0.5 million euros. In 2002 the family business moved into a new main plant in Eltville. Today it describes itself as the largest industrial employer in the Rheingau region and as a training company for technical and commercial occupations. Its brand promise is captured in the slogan "JEAN MÜLLER, the name for safety." Current product families promoted by the company include the modular TOKEO range, the PEGEO distribution and equipment cabinet, the KETO NH fuse switch-disconnector, and the SASILplus fuse switch-disconnector, supported by services such as a retrofit campaign and an online configurator.

The company was founded in 1897 in Eltville by Johann Baptist Müller, known as Jean. Initially occupied with the installation of electrical systems, Jean Müller recognised early on that protecting cables and equipment against short circuits and overloads was very important. He therefore began manufacturing fuse strips and fuses based on the Siemens/Schuckert patent of 1901 and further developing this technology. Fuse technology remains the foundation of the business to this day, and the product portfolio has been continuously expanded over the years with fuse bases, accessories, fuse-based switching devices, and matching enclosures. The company was spared major war damage between 1939 and 1945. In 1946, 100 employees manufactured fuses, and revenue was equivalent to 0.5 million euros. In 2002 the family business moved into a new main plant in Eltville. It is today the largest industrial employer in the Rheingau and a training company for technical and commercial occupations. The company has remained headquartered in Eltville am Rhein since its founding and operates internationally with subsidiaries in Austria, China, Poland, Switzerland, and Singapore, employing around 600 people.
