标准摘要
[中文适用范围]： IEC 60898-1:2015 标准第1章的适用范围如下（除以下修改外）： 在第一段末尾增加以下内容：本标准对除具备上述特性外，还适用于直流运行的单极和双极断路器提出了额外要求。此类断路器的额定直流电压不超过单极220 V、双极440 V，额定电流不超过125 A，额定直流短路分断能力不超过10 000 A。 注：本标准适用于既能分断交流电又能分断直流电的断路器。 删除最后两段。 [外文原描述]： IEC 60898-2:2016 gives additional requirements for single- and two-pole circuit-breakers which, in addition to the above characteristics, are suitable for operation with direct current, and have a rated DC voltage not exceeding 220 V for single-pole and 440 V for two-pole circuit-breakers, a rated current not exceeding 125 A and a rated DC short-circuit capacity not exceeding 10 000 A. This second edition cancels and replaces the first edition published in 2000 and Amendment 1:2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with second edition of IEC 60898-1; b) introduction of test Icn1. This publication is to be read in conjunction with IEC 60898-1:2015 .
