EFEN.
EFEN – your partner for a secure energy future!
A constant and reliable supply of electricity is essential for the well-being of the economy and society. Since distribution networks form the backbone of the energy transition we are striving for, the focus has shifted to electricity distribution and network stability in all areas.
Local distribution networks are already heavily burdened by decentralized solar energy supply. Especially in rural areas, grid operators are often faced with a situation where the energy produced by photovoltaic systems significantly exceeds consumption. This puts too much strain on grids that are not designed to handle the supply of renewable energy.
For you, this means: Facing the challenges ahead in a targeted and thoughtful manner. EFEN’s integrated solutions ensure that you are always on the safe side. As a specialist in safety interfaces, EFEN provides optimized solutions for circuit protection – perfectly adapted to the individual field of application. The systems even meet future requirements: selective network expansion, transformer protection, high-performance solutions for industrial use or compact circuit protection systems for TPS applications.
Components for distribution of electricity.
SAFE DISTRIBUTION OF LARGE CURRENTS
Our focus is on simple installation, responsible handling of energy as a resource and further application-oriented solutions.

SAFE DISTRIBUTION OF LARGE CURRENTS
HV fuses have been providing reliable protection in medium voltage substations and networks for decades. They protect systems and equipment from the thermal and dynamic effects of short circuits.
EFEN HV fuses provide the following significant features:
NH FUSE BOXES
A comprehensive range of EFEN products for the production of switchgear and distributors. The range includes sizes 000 to 3L for all common mounting types, as well as various designs for specific applications. A full range of accessories is available for many connection designs as well as partition walls, contact covers and fuses.





NH FUSE DISASSEMBLER, HORIZONTAL
Perfectly tuned systems with one to four switching poles and sizes from 000 to 3. In DC distribution, compact TPS fuses and load switches save space and costs. A comprehensive assortment of additional equipment enables the implementation of various application-specific solutions.
NH FUSE DISASSEMBLER, VERTICAL
The core competence of EFEN consists of switches with fuses of vertical NH design for safe distribution of electricity. NH vertical design fuse switches offer excellent electrical properties and many upgrade options for smart power distribution.





DISCONNECTOR - FUSE, LOAD CHANGE SWITCHES
EFEN fuses and load change switches are distinguished by their robust functionality and compactness. The range consists of 3- and 4-pole versions, as well as bypass versions with and without fuses.
SMART SOLUTION FOR ELECTRICITY DISTRIBUTION
Requirements for energy distribution in terms of use, functionality and structure are constantly changing. Electric grids are subject to large deviations in energy flow caused by renewable sources. In the future, there will be increased requirements for charging stations for electric vehicles – (e-mobility).
E4-NH FUSE DISCONNECTORS, VERTICAL DESIGN
The E4 series is a standardized series of power distribution devices that offer the basic requirements for a smart power distribution network. A fundamental element of these smart grids for energy distribution is the recording and evaluation of performance data.
E4 products offer the ability to record data easily and conveniently. Years of experience and technical specifications have been invested in the development of this series in order to achieve an optimal result in terms of technical values and safety. The perfect interface for your power distribution that can later be upgraded to different requirements.
