Thermal-links - Requirements and application guide
IEC 60691:2023 is available as IEC 60691:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60691:2023 is applicable to thermal-links intended for incorporation in electrical appliances, electronic equipment and component parts thereof, normally intended for use indoors, in order to protect them against excessive temperatures under abnormal conditions. NOTE 1 The equipment is not designed to generate heat. NOTE 2 The effectiveness of the protection against excessive temperatures logically depends upon the position and method of mounting of the thermal-link, as well as upon the current which it is carrying. This document may be applicable to thermal-links for use under conditions other than indoors, provided that the climatic and other circumstances in the immediate surroundings of such thermal-links are comparable with those in this standard. This document may be applicable to thermal-links in their simplest forms (e.g. melting strips or wires), provided that molten materials expelled during function cannot adversely interfere with the safe use of the equipment, especially in the case of hand-held or portable equipment, irrespective of its position.

Protecteurs thermiques - Exigences et guide d'application
IEC 60691:2023 est disponible sous forme de IEC 60691:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60691:2023 s'applique aux protecteurs thermiques destinés à être incorporés dans les appareils électriques, le matériel électronique et ses composants, normalement utilisés en intérieur, afin de les protéger contre les températures excessives lors de conditions anormales. NOTE 1 Le matériel n'est pas prévu pour produire de la chaleur. NOTE 2 L'efficacité de la protection contre les températures excessives dépend logiquement de la position et du mode de montage du protecteur thermique ainsi que du courant qui le traverse. Le présent document peut s'appliquer aux protecteurs thermiques utilisés dans d'autres conditions que celles qui sont réunies en intérieur, tant que les conditions climatiques ou autres de l'environnement immédiat de tels protecteurs thermiques sont comparables à celles de la présente norme.
Termični taljivi vložki - Zahteve in navodilo za uporabo (IEC 60691:2023)
Ta mednarodni standard se uporablja za termične taljive vložke, namenjene za vgradnjo v električne naprave in elektronsko opremo ter njihove sestavne dele, ki so običajno predvideni za notranjo uporabo, z namenom zagotavljanja zaščite pred prekomernimi temperaturami v izrednih razmerah.
OPOMBA 1: Oprema ni zasnovana za ustvarjanje toplote.
OPOMBA 2: Učinkovitost zaščite pred prekomernimi temperaturami je seveda odvisna od položaja in načina vgradnje termičnega taljivega vložka ter toka, ki ga prevaja.
Ta dokument se lahko uporablja za termične taljive vložke, namenjene za uporabo pri pogojih, ki ne vključujejo notranje uporabe, pod pogojem, da so podnebne in druge razmere v neposredni okolici takih termičnih taljivih vložkov primerljive z razmerami, opisanimi v tem standardu.
Ta dokument se lahko uporablja za termične taljive vložke v najosnovnejši obliki (npr. taljivi trakovi ali žice) pod pogojem, da staljeni materiali, ki se izločijo v primeru uporabe vložkov, ne vplivajo škodljivo na varno uporabo opreme, zlasti pri ročni ali prenosni opremi, ne glede na svoj položaj.
Priloga H tega dokumenta se uporablja za sklope termičnih taljivih vložkov, predhodno odobrenih za uporabo v skladu s tem standardom, ki so vstavljeni v kovinsko ali nekovinsko ohišje in vključujejo priključke/žične vodnike.
Ta dokument se uporablja za termične taljive vložke z naznačeno izmenično ali enosmerno napetostjo, ki ne presega 690 V, in nazivnim tokom, ki ne presega 63 A.
Namen tega dokumenta je:
a) vzpostaviti enotne zahteve za termične taljive vložke,
b) določiti preskusne metode, in
c) podati uporabne informacije za uporabo termičnih taljivih vložkov v opremi.
Ta dokument se ne uporablja za termične taljive vložke, ki se uporabljajo v ekstremnih pogojih, kot so korozivne ali eksplozivne atmosfere.
Ta dokument se ne uporablja za termične taljive vložke, predvidene za uporabo v vezjih izmenične napetosti s frekvenco manj kot 45 Hz ali več kot 62 Hz.
