with IEC 282-1.
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.
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
performance to many other types of 63A rating.
Edison fuses exhibit considerable limitation of current and

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.
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.
