The stress applied to the fuse assembly rated at 125 A is: 0.8 × 10-3 × (16900) 2 = 228 × 103 A 2 s. and even 200 A is unsuitable! This type of bank cannot be protected in this way using for example Fusarc-CF fuses. In some impossible cases, there is a solution that consists of protecting all three banks with a single common fuse (see figure 4).
