The 456SDE 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/60A 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 456SDE 50A/60A Series fuse gives the option of a single fuse solution for protection for such application requirements.


  • Available in ratings of 40A, 50A and 60A
  • Enhanced interrupting rating of 600A@80VDC
  • Very low DC cold resistance, temperature rise and voltage drop
