452 / 454 Series NANO2® Slo-Blo® Fuse
RoHS
¨
2
The NANO Slo-Blo fuse has enhanced inrush
2
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.
The recommended fuse block for the 452 / 454
®
Series Slo-Blo fuse is the SMF OMNI-BLOK
Holder, Series 154 000T.
