Annotation of standard text IEC 60644-ed.2.1+Amd.1-CSV :
IEC 60644:2009+A1:2019 applies primarily to fuse-links used with motors started direct-on-line on alternating current systems of 50 Hz and 60 Hz. Standardizes time-current characteristics to formulate additional pulse withstand requirements regarding testing and to give guidance for the selection of fuse-links to be used with motors. Note: Fuse-links according to this specification should comply with the requirements of IEC 60282-1. The main changes with regard to the previous edition concern the following: - update of the normative references; - renewal of the figures. This consolidated version consists of the second edition (2009) and its amendment 1 (2019). Therefore, no need to order amendments in addition to this publication. LIEC 60644:2009+A1:2019 sapplique principalement aux elements de remplacement utilises avec des moteurs a demarrage direct sur des reseaux en courant alternatif a 50 Hz et 60 Hz. Le but de la presente norme est de normaliser les caracteristiques temps-courant, detablir des specifications dessais concernant la tenue aux impulsions et de donner des conseils pour le choix des elements de remplacement destines a etre utilises avec des moteurs. Note: Les elements de remplacement repondant a cette specification soient conformes aux exigences de lIEC 60282-1. Les changements majeurs par rapport a ledition precedente sont les suivants: - mise a jour des references normatives; - reprise des figures. Cette version consolidee comprend la deuxieme edition (2009) et son amendement 1 (2019). Il nest donc pas necessaire de commander lamendement avec cette publication.
