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.
