DIN CLC/TR 60269-5:2012-06

This Technical Report, which 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. Fuses protect many types of equipment and switchgear against the effects of over-current which can be dramatic: - thermal damage of conductors and bus-bars, - vaporisation of metal, - ionisation of gases, - arcing, fire, explosion, - insulation damage. Apart from being hazardous to personnel, significant economic losses can result from downtime and the repairs required to restore damaged equipment. Modern fuses are common overcurrent protective devices in use today, and as such provide an excellent cost effective solution to eliminate or minimize the effects of overcurrent. The responsible committee is Subcommittee UK 541.1 "Sicherungen und Schalter-Sicherungseinheiten" ("Fuses and fuse-combination units") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
