Automotive blade fuses protect equipment from damage, fire, short circuit (ground touch), or overload; usually, the fuse will trip due to sudden overload.
The properties and requirements of the blade fuses:
- The blade fuses must have stable working characteristics and not operate when an open current and a long-term rated current pass through.
- The A - S characteristic of the blade fuses must be lower than that of the protected object.
- In the event of a short circuit, the tripping fuse must be selective.
- Replacing a blade fuse should be easy and less time-consuming.
