Bussmann Ferrule Fuses

Bussmann’s wide range of Ferrule (cylindrical clip-mounted) fuses are designed and tested to meet the industry’s standard and requirements across the world. Bussmann’s ferrule fuses offer a unique design and provide superior cycling capability and low energy let-through. 

Bussmann Ferrule Fuses

Ferrule fuses are an excellent solution for small UPS, small AC drives and various other low power applications where space is of the essence.

The majority of Bussmann’s ferrule fuses have been tested at their rated voltage except 690V which has been tested to the IEC 60269 standard, requiring clearing at the rated voltage +5%.

Ferrule fuses are often mounted in fuse clips, fuse holders, fuse blocks or fused switches.
