Series Selection Table
Applications
- Industrial equipment
- Semiconductor protection in drives and rectifiers
Selection Notes
- Semiconductor fuses are chosen on I²t let-through against the device surge rating, not on continuous current.
- Termination style: Flush-end contact. Confirm the mating clip or busbar before ordering — ferrule and blade ends are not interchangeable.
