本文件适用于符合IEC 60282-1的电机用熔断器 在50 Hz和60 Hz的交流系统上直接启动。 本文件规定的熔断器应能承受正常使用条件 和电机启动脉冲。 本文件旨在标准化时间-电流特性，并制定 关于试验的脉冲耐受要求。 本文件也适用于与使用辅助起动的电机一起使用的保险丝 在选择熔断器连接的额定电流时已采取了适当的谨慎措施（使用建议 来自IEC TR 62655:2013第5.2.3节和保险丝制造商）。交叉引用:EN 60282-1:2009IEC 60282-1:2009EN 60282-1:2009/A1:2014IEC 60282-1:2009/AMD1:2014IEC/TR 62655:2013取代了BS EN 60644:2009，其中包括以下内容: 修正案，2019年12月

This 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).Cross References:EN 60282-1:2009IEC 60282-1:2009EN 60282-1:2009/A1:2014IEC 60282-1:2009/AMD1:2014IEC/TR 62655:2013Replaces BS EN 60644:2009 which remains currentIncorporates the following:Amendment, December 2019
