Select fuses designed and tested to:
• IEC 269: Part 4
• U.L. Recognized
Bussmann offers a full line of ferrule style (cylindrical and
clip-mounted) fuses, designed and tested to meet standards and requirements in various locations around the
world. Their unique design and construction provide:
• Superior cycling capability
• Low energy let-through (I2t)
Ferrule fuses provide an excellent solution for small UPS,
small AC drives and other low power applications where
space is at a premium.
Voltage Rating
All Bussmann ferrule fuses — except 660 volt — have been
tested at their rated voltage. The 660 volt ferrule fuse has
been tested to the IEC 269 standard, which requires
clearing at the rated voltage +10%.
Accessories
Ferrule fuses may be mounted in fuseclips, fuseholders,
fuseblocks or fused switches. A variety of products are
available to suit most end-use requirements.

Electrical Characteristics
Total Clearing I2t
The total clearing I2t at rated voltage and
at power factor of 15% are given in the
electrical characteristics. For other voltages, the clearing I2t is found by multiplying by correction factor, K, given as
a function of applied working voltage,
E g , (RMS).
