Overview
High speed fuses protect sensitive devices and power semiconductors from short-circuits, and are specifically designed to minimize the I2t, peak let-through current and arc voltage. Our new Bussmann series compact high speed fuses protect compact drives, power conversion and UPS equipment. These 50-400 amp fuses require up to 48% less enclosure space when compared with traditional high speed, round body fuses without compromising heat rise performance.
Bussmann series full range DFJ high speed, current-limiting fuses provide overload and short-circuit protection for variable speed drives and electric controllers, and meet NEC ® branch circuit protection requirements. The DFJ drive fuse has the lowest I2t of any UL branch circuit fuse in the industry to protect power semiconductor devices that utilize diodes, GTOs, SCRs and SSRs.
Key-Features
- Footprint that uses up to 48% less enclosure space allows for a reduction in the overall size of power conversion equipment
- Innovative design allows for a significantly smaller package without compromising heat rise performance
- Global acceptance with UL, CSA and IEC for products sold worldwide
- Traditional installation with a fuse block or bolt-on to busbar for improved design flexibility
