Jean Muller Gmbh Elektrotechnische Fabrik

What Jean Muller Gmbh Elektrotechnische Fabrik does

Jean Müller GmbH Elektrotechnische Fabrik is a privately held German electrical engineering company founded in 1897 and headquartered in Eltville am Rhein, owned by the JEAN MÜLLER Foundation (Stiftung). The company develops and manufactures fuse-based switchgear and enclosures for low-voltage power distribution, with a portfolio of more than 6,000 catalog items centered on NH fuse switch disconnectors (TOKEO, KETO, SL, SASILplus product families), fuse links, enclosures, distribution boards, service entrance boxes, and terminals. Recent product additions (PLVario-II measurement electronics, the PLPlano module, and TOKEO smartgrid) add digital measurement and smart-grid-ready functionality to the electromechanical core, and the JMExpert mobile app with proprietary JM-DTL-Code digital identifiers extends a software/services layer over the hardware offering.

The company serves five primary vertical segments — energy utilities and municipal utilities (primary), data center operators, industrial and switchgear OEMs, the renewable energy sector, and electrical wholesale trade — through a combination of direct field sales in Germany and Europe, wholly-owned subsidiaries in India (Chennai, with manufacturing), Turkey (Ankara), Austria, and Switzerland, regional distributors (notably nine named partners in Turkey), an online catalog at shop.jeanmueller.de, and the JMExpert mobile app. Revenue is generated almost entirely from B2B hardware sales of switchgear and electrical distribution components, with pricing conducted on a quote-based, application-specific basis rather than published list pricing. The company employs 600+ qualified staff at its Eltville headquarters and supports roughly 20 apprentices, operates an approximately 8,000 m² production facility after a 2024 EUR 10 million expansion, and reported ISO 45001 certification in December 2025.
