High speed fuse catalog Reliable protection for semiconductor devices and sensitive electronic equipmentBussmann series high speed fuses High speed fuses protect sensitive devices and power semiconductors from short-circuits, and are specifically designed to 2 minimize the I t, peak let-through current and arc voltage. Typical applications: Protection of AC and DC drives DC common bus Power converters/rectifiers Reduced voltage starters UPS Capacitor protection Switchboard panels Control consoles Our extensive line of high speed fuses offer these styles: North American IGBT fuses Ferrule fuses (round body) British Standard BS 88 Square body fuses Bussmann series high speed fuses also include Compact high speed fuses that require less space 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. UL Listed Class J high speed fuses for full range protection 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 2 drive fuse has the lowest I t of any UL branch circuit fuse in the industry to protect power semiconductor devices that utilize diodes, GTOs, SCRs and SSRs. 2 BUSSMANN SERIES HIGH SPEED FUSE cATALOG 10506 January 2016 Eaton.com/bussmannseries
