HIGH VOLTAGE DIN DISTRIBUTION kV 36 kV FUSES DIN Dimension Fuses To Spec. DIN This product group covers current limiting fuses with dimensions to DIN and performance in compliance with IEC Advantages of Edison High Voltage Current Limiting Fuse The low power dissipation of Edison fuses ensures low temperature rise of switchgear in which they are incorporated. The elements use the ‘M’ metallurgical effect, similar to that used in low voltage fuses. This ensures that, with melting on long time overloads, excessive temperatures are not reached and damage to switchgear components, such as epoxy encapsulating enclosures, is thus prevented. Fuses of Continental European manufacture which in general do not employ this feature are not only hotter running by comparison but also usually need to employ a higher current rating of fuse for the same service thus an Edison 40A fuse is equivalent in terms of thermal performance to many Continental European types of 63A rating. Edison fuses exhibit considerable limitation of current and I2t under short circuit conditions. The stress on circuit components is thereby minimized and the reduction of energy release at the fault reduces fire risks. Switching arc voltages are appreciably less than permitted values and fall with lower values of recovery voltage. The use of, for example, 12 kV fuse on kV systems is therefore permissible.

DIN Dimension Fuses To Spec. DIN This product group covers current limiting fuses with dimensions to DIN and performance in compliance with IEC

Advantages of Edison High Voltage Current Limiting Fuse The low power dissipation of Edison fuses ensures low temperature rise of switchgear in which they are incorporated.

The elements use the ‘M’ metallurgical effect, similar to that used in low voltage fuses. This ensures that, with melting on long time overloads, excessive temperatures are not reached and damage to switchgear components, such as epoxy encapsulating enclosures, is thus prevented. Fuses of Continental European manufacture which in general do not employ this feature are not only hotter running by comparison but also usually need to employ a higher current rating of fuse for the same service thus an Edison 40A fuse is equivalent in terms of thermal performance to many Continental European types of 63A rating.

Switching arc voltages are appreciably less than permitted values and fall with lower values of recovery voltage. The use of, for example, 12 kV fuse on kV systems is therefore permissible.
