b) 5) Rated minimum breaking current for Back-Up fuses (4.8.2)
4.2 Rated voltage
Replace the existing title and text of 4.2 by the following new title and text (keep the existing
Table 3):
4.2 Rated voltage (U )
r
Voltage used in the designation of the fuse-base or fuse-link, from which the test conditions
are determined.
NOTE 1 This rated voltage represents the highest voltage for equipment (see IEC 60038)
NOTE 2 On three-phase solidly earthed systems, fuses may only be used provided that the highest system
voltage is less than or equal to their rated voltage. On single phase or non-solidly earthed systems, fuses may only
be used provided that the highest system voltage is less than or equal to 87 % of their rated voltage, unless
specific testing has been performed (see IEC/TR 62655:2013, 5.1.3).
The rated voltage of a fuse should be selected from the voltages given in Table 3.
4.3 Rated Insulation level (of a fuse base)
Replace the first two paragraphs of 4.3 by the following new text:
"The voltage values (both power frequency and impulse) that characterise the insulation of
the fuse-base with regard to its capability of withstanding dielectric stresses (see
IEC/TR 62655:2013, 4.5).
Two levels of dielectric withstand are recognised for a fuse-base according to European
practice. These are termed "List 1" and "List 2" and relate to different severities of application
and corresponding different values of test voltage for the dielectric tests
(see IEC/TR 62655:2013, 4.5.2)."
4.6 Rated current of the fuse-link
Replace the existing title and first paragraph of 4.6 by the following new title and text:
4.6 Rated current of the fuse-link (I )
r
The current assigned to the fuse-link that a new clean fuse-link will carry continuously without
exceeding specified temperature rises when mounted on a fuse-base specified by the
manufacturer and connected to the circuit with certain specified conductor sizes and lengths,
at an ambient air temperature of not more than 40 °C (see IEC/TR 62655:2013).
4.7 Temperature-rise limits
Replace the existing Note by the following two new Notes:
NOTE 1 For fuses used in enclosures, see 6.5.3, and IEC/TR 62655:2013, 5.1.1.2 and Annex A.
NOTE 2 Therefore where the term "oil" is used in this standard, any appropriate insulating liquid is covered.
Appropriate insulating liquids are those approved by the fuse manufacturer.

Replace Footnote f with the following new footnote:
f Special consideration should be given with regard to vaporisation and oxidation when low-flash-point oil is
used. The given temperature value may be exceeded for transformer-type applications and/or if synthetic or
other suitable insulating liquids are used (see 7.7.3 and IEC 60076-7).

b Duration of travel is defined as the time from commencement of arcing to the time when travel OB is reached.
The minimum arcing withstand time of 100 ms (4.15.3) is sufficient to cover this 50 ms plus an additional time
of 50 ms to allow for the switching device operating time.
5.1.1 General
Replace the third paragraph of 5.1.1 with the following new text:
"No tests have been specified to prove the performance of the fuse in the range of currents
below that specified in the breaking tests in 6.6 with respect to its capability to withstand the
current of every possible time/current combination without deterioration leading to either
premature operation or failure (see IEC TR 62655:2013)."
5.1.2 Standard conditions of use
Replace the existing text of 5.1.2 by the following new text:
Testing specified in this standard is intended to demonstrate the suitability of a fuse for use
under the following conditions:
• the a.c. component of current is not higher than the rated maximum breaking current;
• the a.c. component of a current that the fuse is intended to interrupt is not lower than:
– the rated minimum breaking current for a Back-Up fuse;
– the current that causes melting in 1 h for a General-Purpose fuse;
– the rated current for a Full-Range fuse;
• the surrounding temperature is not higher than the maximum application temperature
(MAT) in the case of a Full-Range fuse that has an assigned MAT (with no
