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.
Available in ratings of 40 to 50A
High interrupting rating - 600A@75VDC
Very low cold resistance, temperature rise, and voltage drop
High inrush/surge current withstand capability
Surface mountable high current fuse
Single fuse solution for high current application
Suitable for a wide variety of voltage requirement and application
Enhances power efficiency
Avoids nuisance opening due to high inrush and surge current inherent in the system
