管ヒューズ 20A 55 x 520mm 24kV ac 超速断型 1袋 3個入

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
