452/454 Series Fuse

Description

The NANO

Slo-Blo

fuse has enhanced inrush withstand

characteristics over the NANO

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.
