Low-voltage fuses - Part 5: Guidance for the application of 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 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
Fusibles basse tension - Partie 5: Lignes directrices pour l'application des fusibles basse tension
L'IEC/TR 60269-5:2014 est un guide d'application des fusibles basse tension, montre que les fusibles limiteurs de courant sont faciles à utiliser pour protéger le matériel électronique complexe et sensible d'aujourd'hui. Ces lignes directrices couvrent spécifiquement les fusibles basse tension de tensions jusqu'à 1 000 V en courant alternatif et 1 500 V en courant continu selon la série IEC 60269. Elles fournissent des informations sur les fusibles ainsi que sur leurs applications. Cette deuxième édition annule et remplace la première édition parue en 2010. Cette édition constitue une révision technique. Cette édition comporte les modifications techniques suivantes en rapport avec l'édition précédente:
- les recommandations et préconisations pour le fonctionnement des fusibles à des altitudes supérieures;
- l'ajout d'informations concernant les différentes tensions de fonctionnement des fusibles;
- l'ajout de recommandations pour la protection des systèmes photovoltaïques;
- l'amélioration de nombreux détails. Mots clés: guide d'application des fusibles basse tension, les fusibles limiteurs de courant
Nizkonapetostne varovalke - 5. del: Navodila za uporabo nizkonapetostnih varovalk
IEC/TR 60269-5:2014 se uporablja kot navodilo za uporabo nizkonapetostnih varovalk in prikazuje, kako je varovalke, ki omejujejo tok, enostavno uporabiti za zaščito današnje kompleksne in občutljive električne ter elektronske opreme. Ta navodila posebej obravnavajo nizkonapetostne varovalke do 1000 V izmenične napetosti in 1500 V enosmerne napetosti, ki so zasnovane in izdelane v skladu s skupino standardov IEC 60269. V teh navodilih so podana pomembna dejstva in informacije o uporabi varovalk. Druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno leta 2010. Ta izdaja je tehnično popravljena izdaja. Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
– priporočila za delovanje varovalk na visokih nadmorskih višinah,
– več podrobnosti za delovne napetosti,
– priporočila za zaščito fotonapetostnega sistema,
– številne podrobnosti izboljšanih ključnih besed: navodila za uporabo nizkonapetostnih varovalk, varovalke za omejevanje toka
