452/454 Series Fuse
Description
The NANO
2
Slo-Blo
®
fuse has enhanced inrush withstand
characteristics over the NANO
2
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.
