IEC 61000-3-3:20 13+A1:2017+A2:2021涉及对公共低压系统施加的电压波动和闪烁的限制。它规定了在特定条件下测试的设备可能产生的电压变化的限制，并给出了评估方法的指导。它适用于每相输入电流等于或小于16A的电气和电子设备，旨在连接到220 V和250 V之间的公共低压配电系统，以50 Hz的频率连接到中性线，并且不受条件连接的限制。IEC 61000-3-3具有IEC 61000系列中的产品系列标准的地位。这第三版取消并取代了2008年出版的第二版。本版本是一个技术修订版，考虑了IEC 61000-4-15:2010.该合并版本由第三版（2013年）、修正案1（2017年）和修正案2（2021年）组成。因此，除了本出版物之外，没有必要下令进行修订。

IEC 61000-3-3:2013+A1:2017+A2:2021 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. It is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection. IEC 61000-3-3 has the status of a product family standard within the IEC 61000 series. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision which takes account of the changes made in IEC 61000-4-15:2010. This consolidated version consists of the third edition (2013), its amendment 1 (2017) and its amendment 2 (2021). Therefore, no need to order amendments in addition to this publication.
