Transformer fuse Limitor® - NF/UTE series

cartridgecompactcurrent-limiting

Approvals & Standards IEC 60282-1 • UTE C64-210 FR-type fuses are designed to protect HV/LV power distribution transformers. Designed to be coordinated with other equipment, these current limiting fuse-links interrupt fault currents before they reach their peak. The fault current is interrupted inside the fuse-link body and although this is very fast, there is no sign of it outside. The 24kV fuses were specially designed with very low power losses, for use in SF6-insulated or compact air-insulated fused switchgear combinations The main elements in these fuses are: a barrel of class F insulating synthetic material, nickel plated aluminium end contacts, pure silver fuse elements and a composite material fuse element holder to withstand high temperatures. Thanks to their structure, based on a synthetic material, FR fuse-links are the perfect answer to the stress involved in use inside HV bays and fuse-link chambers. Superior mechanical strength • Outstanding withstand to operating stresses • 100% synthetic structure • Reduce power losses by 30 to 40% (24kV) • Average type striker: force 1 ±0.5 Joules • High breaking capacity • High current limitation • EDF Approval which guarantees high performances and quality of fuses manifactured (24kV) • In accordance with: • IEC 62271-105 • IEC 62271-107 • IEC 60787 • IEC/TR 62655
