Fast acting fuses are better option when we require to couple a low Short circuit rated network to an infinite bus or network with high short circuit rating. IS limiting fuses are also desirable when coupling two or more LV networks with moderately high short circuit rating where the combined Short circuit rating of the coupled network exceeds technically feasible values. In such cases by inserting fuses with proper clipping current characteristics, we can limit the short circuit rating of the coupled networks.
