Description

General part information

0456050.SD Series

The 456SD Series NANO²® fuse is a small sized, surface-mountable high current fuse which provides over-current and excessive surge current protection for applications operating at high current in a limited space. This will be a supplementary offering to the existing 456 and 881 Series where the 50A fuse rating is not available. Such applications are mostly served today through a single large-sized high-current industrial type fuse or in some cases, parallel configuration of lower amperage SMD fuses. The 456SD 50A Series fuse gives the option of a single fuse solution for protection for such application requirements.
