Fuses
300/600V Current Limiting Fuse
Features
High-functioning, high-capacity fast current limiting fuse suited for protective use of semiconductors.
Usable body of this fuse is manufactured by a innovative, patented manufacturing process, which leads to a marked improvement in fusing and interruption capacity as well as mechanical strength.
Furthermore, this product has passed UL certified test based on UL248 standards.
- High interruption capacity and excellent current limiting
- Has very low I2T and voltage, which makes it suitable for semiconductor protection
- Is uniform and doesn’t undergo age deterioration
- Small and light, which makes the overall machine smaller
- Can interrupt DC
- UL certification: E148347
