Seminconductor protection fuses are very fast-acting fuses specifically designed for the protection of power semiconductors such as IGBT,IGCT,GTO,SCR and etc.Generally,semiconductor devices have a very expensive and very limited over-load capacities.Therefore,it is worth to produce fuses which are more sensitive to overloads and which can operate more quickly than the conventional designs.<br />
Seminconductor protection fuses have lower let-through I²t and arc voltage than do traditional fuses in accordance with IEC 60269-4 have traditionally been "partial range"or "back-up" fuses and are given the designation or utilization category of "aR".As protection solutions and practice have developed ,there is a growing need for fuses with "full range"breaking capacity.Therefore,two kinds of full range breaking capacity classifications were introduced into IEC 60269-4 namely "gR" and "gS" fuses are optimized to low I²t and "gS" optimized to low power dissipation.<br />
