3.6kV – 36kV High Voltage DIN Distribution Fuses

Edison fuses exhibit considerable limitation of current and

This product group covers current limiting fuses with

dimensions to DIN 43.625 and performance in compliance

with IEC 282-1.

I t 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, 12kV fuse on 6/7.2kV

systems is therefore permissible.

Advantages of Edison High Voltage Current - Limiting

Fuses

The low power dissipation of Edison fuses ensures low

temperature rise of switchgear in which they are

incorporated.

Striker Characteristics

The spring operated striker pin has a travel and energy

output in compliance with the requirements of DIN 43625

and IEC 282-1.

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 that 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

Selection of these fuses has been based on a compromise between the following:

1. The fuse should withstand transformer magnetizing inrush currents, taken as 12 times full load current for 0.1 second.

2. The fuse should coordinate with the highest rating of the secondary fuse likely to be used.

3. The fuse should operate reasonably quickly in the event of a transformer inter-turn fault or a fault in the secondary terminal zone of the transformer.

NOTES:

A. In general, the recommendations apply equally to the use of fuse in open air or in an encapsulated enclosure, since “1” and “2” above dictate the use of a

fuse current rating sufficiently above the transformer current rating to nullify any adverse thermal affect of encapsulation. However, if the transformer is

subjected to long time overcurrents, a higher rate of fuse may be required.

B. The above recommendations are not generally applicable to transformers feeding motor circuits with starting currents in excess of the rated current of the

fuse. In this event, please consult your local Edison representative.

C. Recommendations for other voltages are available on request.

D. While the above recommendations give a good general guide, recommendations for specific cases will be sent on receipt of full details of the application.
