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.
