NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical with IEC 60269-2 : 2016 ‘Low-voltage fuses — 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’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Fuses Sectional Committee and approval of the Electrotechnical Division Council.

This standard is adopted based on IEC 60269-2 : 2016 (Ed 5.1) ‘Low-voltage fuses — 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’. However, certain references within the standard are missing and therefore in order to address these references a national annexure has been incorporated in the standard and given as National Annex A. These references have been drawn from IEC 60269-2 (Ed 5.0).

This standard supersedes IS 13703 (Part 2/Sec 1) : 1993 ‘Low-voltage fuses for voltages not exceeding 1 000 V AC or 1 500 V DC: Part 2 Fuses for use by authorized persons, Section 1 Supplementary requirements’ and 13703 (Part 2/Sec 2) : 1993 ‘Low-voltage fuses for voltages not exceeding 1 000 V ac or 1 500 V dc: Part 2 Fuses for use by authorized persons, Section 2 Examples of standardized fuses’.

This part is to be used in conjunction with IS/IEC 60269-1 : 2014, Low-voltage fuses — Part 1: General requirements. This Part 2 supplements or modifies the corresponding clauses or subclauses of Part 1. Where no change is necessary, this Part 2 indicates that the relevant clause or subclause applies. Tables and figures which are additional to those in Part 1 are numbered starting from 101. Additional annexes are numbered AA, BB, etc.
