Amendment 1 - Low-voltage fuses - Part 5: Guidance for the application of low-voltage fuses

Scope

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 first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- recommendations for fuse operations in high altitudes added,
- more details for operational voltages added,
- recommendations for photovoltaic system protection added,
- numerous details improved Keywords: application guide for low-voltage fuses, current-limiting fuses
