Description

General part information

452 Series

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.
