Siba fuses | High voltage

Description

High-voltage fuse-links (HV fuse-links) are used as protection devices in medium voltage switchgear. The great advantage is the very fast current limiting operation in the event of short-circuit failures. Consequently, they protect switchgear and equipment against dynamic thermal effects of such shortcircuits in a very effective way.

SIBA HV fuse-links comply with the following standards:

  • IEC 60282-1 / VDE 0670 parte 4
  • IEC 60787 / VDE 0670 parte 402
  • DIN43625
  • IEC 60644 / VDE 0670 parte 401
  • IEC 60549
  • IEC 62271 parte 105

Range of SIBA HH fuses in high voltage that is marketed by Pronutec is divided in:

HHD-B: A classical standard back-up fuse for transformer protection and distribution (<2000 kVA).
HHD-BSSK: Back-up SSK fuses can be used for transformers with higher power ratings (≥630 kVA) with low power losses.
