Surface Mount Fuses NANO2® > Slo-Blo® Fuse > 452/454 Series 452/454 Series Fuse RoHS PS E Description The NANO2® Slo-Blo® fuse has enhanced inrush withstand characteristics over the NANO2® Fast-Acting fuse. The unique time delay feature of this fuse design helps solve the problem of nuisance “opening” by accommodating inrush currents that normally cause a fast-acting fuse to open.
