Integrated backup fuse
Circuit Interruption (CI)
According to the product standard for surge protective devices (SPDs), overcurrent protective devices / backup fuses must be used. This, however, requires additional space in the distribution board, additional cable lengths, additional installation time and costs as well as dimensioning of the fuse. A fuse integrated in the arrester which is ideally suited for the impulse currents involved eliminates all these disadvantages.
Products with integrated backup fuse from DEHN stand out due to their reduced space requirements, lower wiring effort and reduced installation costs. In addition, the integrated fuse monitoring and the increased protective effect resulting from the shorter connecting cables are further advantages of this concept.
