The centrepiece for safe energy distribution
Developed from traditional core expertise, EFEN offers a broad selection of NH fuse-links in accordance with IEC/DIN standards for low voltage in the areas of cable, line and transformer protection and converter system protection as well as HV fuses for medium voltage. In addition to standard applications, EFEN offers a wide range of fuse-links for special applications. These include NH fuse-links for TPS and DC applications.
NH fuse-links
- A complete system of NH fuse-links based on the latest technology
- Significantly reduced power output of the 400 V NH fuse-links, less heating
- Combination indicator guarantees visibility in various applications
- Application-specific characteristic curves, e.g. gG for cable and line protection, gTr for transformer protection, gR/aR for converter system protection
- A wide range of accessories as well as special versions, e.g. with impact detectors, battery fuses and industrial safety fuses, offer a variety of application options
NH fuse-links for DC applications
- EFEN battery fuses offer optimum DC switching behaviour
- Protection of (UPS) batteries against overheating and mechanical damage in the event of a short circuit
- Reduced heat emission due to low power loss
- Complete range of battery fuses and switches enables optimum protection of all common UPS systems up to 550 V battery voltage
- Compact design of the TPS Fault Terminator fuses, application only with TPS disconnector.
- Expert support from EFEN when selecting the fuse characteristics. A survey is available here for the required information.
- NH fuse-links up to 550 V – Survey EFEN battery switches and battery fuses for UPS systems
D fuse-links
With the D-fuse links, you get protection in the smallest of spaces, which can be perfectly integrated into the systems of the future thanks to modern distribution components from EFEN.
HV fuses
- Multi-range and partial-range fuses for rated voltages of 3.0 kV to 40.5 kV from EFEN in accordance with VDE 0670 T4 and also VDE 0670 T402 / IEC 60 282-1
- Reliable safety interfaces for transformers, condensers and high-voltage motors
- The EFEN range includes types for indoor, outdoor and submerged oil applications
- National and international approvals
- Due to their design, EFEN HV fuses limit the current within milliseconds so that the peak value in the sinusoidal current curve is not reached
