Reliable protection for
semiconductor devices
and sensitive electronic
equipment
Bussmann® series high speed fuses
High speed fuses protect sensitive devices and power
semiconductors from short-circuits, and are specifically designed to
minimize the I
2
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
(round body)
IGBT fuses
Ferrule fuses
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
drive fuse has the lowest I
2
t of any UL branch
circuit fuse in the industry to protect power
semiconductor devices that utilize diodes,
GTOs, SCRs and SSRs.

New high speed fuse
application guide
This 36-page application guide helps users understand
the dynamics involved in the high speed fuse
specification and selection process.
It covers high speed fuse characteristics,
performance data, application in AC and DC
systems along with worked examples that
explore the influence of overloads and cyclic
loadings, and safety margins.
Other topics include international
standards, Bussmann series high speed
fuse reference systems along with
installation, service, maintenance
tips.
