Technological excellence

Quality, expertise and innovation – what has set us apart for over 120 years has now made an international name for itself: “The Name of Safety”. Our customers therefore rightly demand not merely the first-best, but always the best possible solutions – for the most exacting safety requirements, first-class consulting services and an unparalleled product range.

Because reliability is a matter of course for us, we are happy to shoulder this responsibility thanks to our “Made in Germany” philosophy. This is evidenced at our site in Eltville and in our more than 600 qualified employees.

Experience, expertise and fresh inspiration

Our services start with well-founded advice for our users, continue with state-of-the-art production and assembly techniques and culminate in completely new, individual solutions. Because we design and produce the tools ourselves, our customers benefit from an outstanding level of flexibility – with rapid prototyping and simulation programs, fast implementation of innovations and dependable punctuality when just-in-time deliveries are needed.

Whether for fuse-switch-disconnectors, energy monitoring systems or service entrance boxes – you can count on JEAN MÜLLER for safety and service!
