IEC 60252-1:20 0+A1:2013适用于用于连接到由频率高达且包括100Hz的单相系统供电的异步电动机的绕组的电动机电容器，以及用于连接到三相异步电动机的电容器，使得这些电动机可以由单相系统供电。本标准涵盖具有纸、塑料膜或两者组合电介质的浸渍或未浸渍电容器，金属化或带有金属箔电极，额定电压高达660 V（含660 V）。与上一版相比，此版本包括以下重大技术变更: -3.6中增加了“分段电容器”的定义； -澄清“操作类别”的定义， 加入“可能寿命”的概念，参考 统计，在3.9； -以下措辞“在额定电压以上运行将 降低电容器的预期寿命”已在 6.1. -在第8条“标记”中加入了一些澄清，主要是 对于小型电容器。 本合并版本由第二版（2010年）组成 及其修正案1（2013年）。因此，无须在 本出版物的补充。

IEC 60252-1:2010+A1:2013 applies to motor capacitors intended for connection to windings of asynchronous motors supplied from a single-phase system having a frequency up to and including 100 Hz, and to capacitors to be connected to three-phase asynchronous motors so that these motors may be supplied from a single-phase system. This standard covers impregnated or unimpregnated capacitors having a dielectric of paper, plastic film, or a combination of both, either metallized or with metal-foil electrodes, with rated voltages up to and including 660 V. This edition includes the following significant technical changes with respect to the previous edition:
- the definition of "segmented capacitors" has been added in 3.6;
- the definition of "classes of operation" has been clarified, with the addition of the concept of "probable life" with reference to statistics, in 3.9;
- the following wording "Operation above the rated voltage will reduce the life expectancy of the capacitor" has been introduced in 6.1.
- some clarifications have been added to Clause 8, Marking, mainly for small capacitors. This consolidated version consists of the second edition (2010) and its amendment 1 (2013). Therefore, no need to order amendment in addition to this publication.
