Reliable protection for semiconductor devices and sensitive electronic equipment
●High speed fuses protect sensitive devices and power semiconductors from short-circuits, and are specifically designed to minimize the I2 t, 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 I2 t of any UL branch circuit fuse in the industry to protect power semiconductor devices that utilize diodes, GTOs, SCRs and SSRs.
