Round body fuses
- 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)
