NANO^2®Slo-Blo^®Fuse 452/454 Series

RoHS

The NANO²Slo-Blo fuse has enhanced inrush withstand characteristics

over the NANO²Fast-Acting fuse. The unique time delay feature of this

fuse design helps solve the problem of nuisance “opening” by accommo-

dating 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).
