**50 percent of fuse label amp rating tested at 23°C ± 2°C.


Dimensions† — mm




  • Agency information

    • Designed to:

      • JASO D622

      • ISO 8820-8

    • Manufactured under a IATF 16949 quality system for compliance with automotive requirements

    • RoHS compliant

    • REACH declaration available upon request


    Features

    • • Higher voltage rating provides overall system efficiency using smaller, more economical conductors while meeting the needs of higher voltage battery packs

      • Higher interrupting rating protects high capacity battery packs needed for vehicle acceleration and range requirements

      • Up to ten times faster opening under high fault current conditions helps assure reliable protection of circuits and components

      • Requires up to 48% less space than conventional high speed fuses to help reduce space and weight

      • Data logging system marks each fuse with a serial number and date code for traceability of Critical to Quality characteristics

      • To help project the life of the fuse in your application, unique driving profiles and conditions can be simulated to verify proper fuse size and performance under a wide range of driving behaviors

      • Operation as low as 200% overload provides back up protection to the battery management system

      • Can be applied in parallel to realize greater ampacity within sizing guidelines
