Specification for high-voltage fuse-links for motor circuit applications

(IEC 60644:2009 + A1:2019); German version EN 60644:2009 + A1:2019
Class/Status: Standard, valid
Released: 2020-08
VDE Art. No.: 0600277

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.
