High Voltage Fuses
Bussmann's high voltage fuses start from 1000V. Their core high voltage fuse range starts from 3.6kV ('A' and 'W' range current limiting back-up fuse links) up to 36kV ('T' range current limiting back-up fuse links).
Bussmann's high voltage fuse links feature a M-effect design to enhance performance. The M-effect design consists of applying overlay spots of special low melting alloy onto the fuse element strips. It ensures that the fuse link runs cooler in service and that the maximum temperature reached during fuse operation is kept down to 160°C, compared to 300-400°C for fuse links which do not employ this feature.
The M-effect has been used across both the low voltage and high voltage fuse links of British designs for many years, providing a longer service life with many remaining inert for 30 years or more. M-effect fuse links are also safer than alternative designs - they provide better protection and last much longer.
