当相关产品标准要求时，IEC 60947-1:20 20适用于低压开关设备和控制设备，以下称为“设备”或“装置”，旨在连接到额定电压不超过1 000 V AC或1 500 V DC的电路。 本文件规定了低压开关设备和控制设备的一般规则和常见安全要求，包括: -定义； -特性； -随设备提供的信息； -正常使用、安装和运输条件、退役和拆卸； -结构和性能要求； -特性和性能的验证； -能源效率方面（见附件五）； -环境方面。 本第六版取消并取代2007年出版的第五版，修正案1:2010和修正案2:20 14。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: -DC值测试改进； -更新EMC测试； -删除附件B； -更新环境测试要求（表Q.1）； -改进附件R（新实例）； -在附件S中删除数字输入类型2，并引入类型3； -材料申报示例（附件W）； -创建了新的附件X（同一电路中相关短路保护装置之间的协调）。

IEC 60947-1:2020 applies, when required by the relevant product standard, to low-voltage switchgear and controlgear hereinafter referred to as "equipment" or “device” and intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V AC or 1 500 V DC.
This document states the general rules and common safety requirements for low-voltage switchgear and controlgear, including:
- definitions;
- characteristics;
- information supplied with the equipment;
- normal service, mounting and transport conditions, decommissioning and dismantling;
- constructional and performance requirements;
- verification of characteristics and performance;
- energy efficiency aspects (see Annex V);
- environmental aspects.
This sixth edition cancels and replaces the fifth edition published in 2007, Amendment 1:2010 and Amendment 2:2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
– DC values testing improvement;
– update of EMC tests;
– Annex B deletion;
– update of requirements for environmental tests (Table Q.1);
– improvement of Annex R (new examples);
– deletion of digital input Type 2, and introduction of Type 3 in Annex S;
– example for materials declaration (Annex W);
– new Annex X (co-ordination between short-circuit protective devices associated in the same circuit) created.
