Fuses+holders 2-poles for protection of Type 1 AC SPD
Part Number: 64055
SFD1-25S-20
- Specific Fuses (SPD Fusing Disconnectors) for short circuit protection of AC SPD
- For Type 1 SPD
- Surge current withstand: 25 kA (@10/350µs)
- Very compact
- Included fuses
- 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.
