NATIONAL FOREWORD

This Indian Standard (Part 7) which is identical to IEC 60269-7 : 2021 'Low voltage fuses - Part 7: Supplementary requirements for fuse-links for the protection of batteries and battery systems' issued by the International Electrotechnical Commission (IEC), was adopted by the Bureau of Indian Standards on the recommendation of the Fuses Sectional Committee and approval of the Electrotechnical Division Council.

This standard is published in several parts. The other parts in this series are:

Part 1 General requirements

Part 2 Supplementary requirements for fuses for use by authorized persons (fuses mainly for industrial application ) - Examples of standardized systems of fuses A to K

Part 3 Supplementary requirements for fuses for use by unskilled persons (fuses mainly for household and similar applications ) - Examples of standardized systems of fuses A to F

Part 4 Fuse-links for the protection of semiconductor devices - Supplementary requirements

Part 5 Guidance for the application of low-voltage fuses

Part 6 Supplementary requirements for fuse-links for the protection of solar photovoltaic energy systems

The text of the IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appears referring to this standard, they should be read as 'Indian Standard'; and

b) Comma (,) has been used as a decimal marker, while in Indian Standards the current practice is to use a point (.) as the decimal marker.
