  • Specific Fuses (SPD Fusing Disconnectors) for short circuit protection of AC SPD
  • For Type 1 SPD
  • Surge current withstand: 12.5 kA (@10/350µs)
  • Very compact
  • Fuses included
  • Remote signaling and status signaling

The SFD range has been especially designed to associated with Type 1 SPDs. These very specific fuses are able to conduct huge surge currents in rather small dimensions to protect Type 1 SPDs against harsh current circuit failures. In order to comply IEC 61643-11 standards, AC power SPD must be protected against short circuit failures: these specific fusing disconnectors must be installed in the SPD branch.
