DESCRIPTION

UNE EN 60644:2010/A1:2020

Replace the existing text by the following new text: This standard applies to fuse-links complying with IEC 60282-1 that are used with motors started direct-on-line on alternating current systems of 50 Hz and 60 Hz. Fuse-links according to this specification are intended to withstand normal service conditions and motor starting pulses. The purpose of this standard is to standardize time-current characteristics and to formulate pulse withstand requirements regarding testing. This standard also applies to fuse-links used with motors that use assisted starting when appropriate care has been taken with selecting the rated current of the fuse-link (using advice from 5.2.3 of IEC/TR 62655:2013 and from the fuse manufacturer).
