A1_startThis document 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 document are intended to withstand normal service conditions and motor starting pulses.

The purpose of this document is to standardize time-current characteristics and to formulate pulse withstand requirements regarding testing.

This document 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).
