SC 32B - Low-voltage fuses

IEC/TR 60269-5:2014 serves as an application guide for low-voltage fuses, shows how current-limiting fuses are easy to apply to protect today's complex and sensitive electrical and electronic equipment. This guidance specifically covers low-voltage fuses up to 1 000 V a.c. and 1 500 V d.c. designed and manufactured in accordance with IEC 60269 series. This guidance provides important facts about as well as information on the application of fuses. This second edition cancels and replaces the firs...view more

IEC 60269-2:2013 provides supplementary requirements for fuses for use by authorized persons and are generally designed to be used in installations where the fuse-links are accessible to, and may be replaced by, authorized persons only. Fuses for use by authorized persons according to the following fuse systems also comply with the requirements of the corresponding subclauses of IEC 60269-1, unless otherwise defined in this standard. This standard is divided into fuse systems, each dealing with ...view more

The contents of the corrigendum of March 2013 and of June 2013 have been included in this copy.

IEC 60269-6:2010 gives supplementary requirement to those given in IEC 60269-1 for fuse-links for protecting photovoltaic (PV) strings and photovoltaic (PV) arrays in equipment for circuits of nominal voltages up to 1 500 V d.c.
This publication is to be read in conjunction with IEC 60269-1:2006.

IEC 60269-3:2010 provides supplementary requirements for fuses for use by unskilled persons according to the following fuse systems comply with all subclauses of IEC 60269-1 and with the requirements laid down in the relevant fuse systems. This part is to be used in conjunction with IEC 60269-1, Low-voltage fuses - Part 1: General requirements. This Part 3 supplements or modifies the corresponding clauses or subclauses of Part 1.
