NANO2® Slo-Blo® Fuse 452/454 Series
®
RoHS
®
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.
• 452 Series RoHS Compliant version now available, use ordering suffix ‘L’
(see example on data sheet).
