This product group covers current limiting fuses with dimen-
sions to DIN 43.625 and performance in compliance with
IEC 282-1.
Advantages of Edison High Voltage Current -
Limiting Fuse
The low power dissipation of Edison fuses ensures low tem-
perature 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 melt-
ing 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 com-
parison but also usually need to employ a higher current rat-
ing 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
I
2
t under short circuit conditions. The stress on circuit com-
ponents 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 6/7.2 kV systems is
therefore permissible.
Striker Characteristics
The spring operated striker pin has a travel and energy out-
put in compliance with the requirements of DIN 43625 and
IEC 282-1.
Travel is approx. 26mm
Energy Output is approx. 0.6 joule

*Fuse rated 15.5kV max.
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 seconds.
2.The fuse should discriminate 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 cur-
rent 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 office.
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.
