Fuse-Links: low- and medium-voltage applications | EFEN GmbH

The Core of Safe Power Distribution

Rooted in our traditional core competence is EFEN’s comprehensive range of fuse-links according to IEC/DIN standards for low-voltage and medium-voltage applications. Innovative high-tech products protect people and investments and ensure maximum availability.

EFEN’s offering comprises the entire system of NH Fuse-Links for wiring and line protection as well as transformer and machinery protection. In addition to standard applications, we also offer a variety of products for specific applications. These include ESS fuse-links for energy storage systems and NH fuse-links for DC applications. Here, specific DC fuses are required since the performance data differ significantly from AC applications. For reliable section protection and high cut-out currents of photovoltaic systems, fuse-links of size 10×38 are available.

Fuse-links by EFEN comply with national and international standards and regulations such as DIN/IEC 60269 and VDE 0636.

EFEN’s general-purpose and back-up fuse-links are a reliable safety interface for transformers, capacitors and high-voltage motors. The range includes types for indoor, outdoor and oil-submerged applications and is nationally and internationally approved.
