Fuses - Electric Vehicle

500 Vdc battery power and auxiliary fuses up to 400 A

Eaton’s Bussmann series Electric Vehicle (EV) full range fuses for vehicle systems up to 500 Vdc

20, 25 and 30mm diameter fuses from 50 to 400 amps protect high power battery charging and management systems.

10x38mm ferrule, bolt-on or PCB terminal fuses from 5 to 50 amps protect auxiliary electrical systems.

  • 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
  • Are available in three case diameters and sizes:
    • 20 mm (50 to 150 amps)
    • 25 mm (100 to 250 amps)
    • 30 mm (200 to 400 amps)
