Conventional fuses and their disadvantages
The graph opposite illustrates this correlation. It shows the maximum disconnection time of a conventional fuse with a rated current of 1A compared to the disconnection behaviour of our EFUSE electronic fuse. For example, in the case of the conventional fuse (red curve), the disconnection time at 1.5-times the rated current is more than 16.6 minutes. This shows the huge advantage of the EFUSE (blue curve), which identifies this same level of overcurrent and disconnects the current flow within 0.1 seconds, thereby protecting the connected device from damage.
The benefits of the EFUSE electronic fuse
Compared to a conventional fuse, the EFUSE exhibits minimal electrical resistance, which results in much more detailed playback – a difference you really can hear. If a fault occurs, the EFUSE immediately interrupts the current flow, thereby protecting your equipment from further damage. Indeed, there is another advantage to the EFUSE besides significantly better playback. Since it deactivates connected devices much faster and more precisely, your valuable equipment benefits from much wider protection. That is not the case when using a conventional fuse.
Operating current is fed to the connected device through a high-quality, gold-plated grounding-type plug (German domestic standard) and connector designed for use with low-temperature devices (IEC standard). Generously dimensioned, high quality and shielded cables also ensure minimal contact resistance, while the shielding of the cable also protects against unwanted interference.
