452 / 454 Series

NANO

Slo-Blo®

Fuse

RoHS

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.

The recommended fuse block for the 452 / 454

Series

Slo-Blo

fuse is the SMF

OMNI-BLOK

Holder, Series 154 000T.
