  • Specific Fuses (SPD Fusing Disconnectors) for short circuit protection of Type 1 AC surge protectors
  • Surge current withstand: 25 kA @ 10/350µs
  • Very compact
  • Fusion signaling feature
  • Remote signaling though fuse holder

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 msut be installed in the SPD branch. The SFD are equipped with fusing indicator to be used inside holder with remote signalling feature. The SFD disconectors must be used with specific fuse holders which provide : - relevant surge current capability - remote signaling feature - switching (useful for maintenance purpose)
