Fusibile a cartuccia Mersen FR, 63A, Ø 55 x 520mm, FF, 24kV ac

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.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
