The new 507 Series Cartridge Fuse from Littelfuse is ideal for over-current protection in high-voltage DC power circuits. Its small footprint simplifies creating compact designs for power conversion equipment that demands higher operating efficiencies. It is available in both standard cartridge and axial-leaded designs, is RoHS compliant and 100% lead free.

Typical applications for the 507 Series include over-current protection for variable frequency drives (VFDs), photovoltaic (PV) inverters, DC-DC converters, high-voltage power supplies, etc.
