IEC 60947-6-2:20 20本文件适用于控制和保护开关装置（或设备）（CPS），其主触点旨在连接到额定电压不超过1 000 V AC或1 500 V DC的电路。它涵盖了控制和保护开关设备（CPS）:其为电路和电机提供保护和控制功能;其控制功能仅以非手动方式操作；其在过电流条件之后提供服务的连续性；和其可以具有附加功能，例如隔离或通信。本第三版取消并取代2002年出版的第二版及其修正案1:20 07。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:根据ISO/IEC指令第2部分进行编辑变更，与IEC 60947-1:20 20的一致性:标记(“s”、“sol”、“r”或“f”)；结构要求，包括材料要求；无螺丝端子的要求；磁极阻抗的测量方法；EMC要求和测试；确定功能安全应用中使用的机电CPS数据的程序；与IEC 60947-2:20 16的协调:欠压继电器和分流脱扣器的操作试验；IT系统的CPS（附件G）；与其他短路保护装置的配合；与IEC 60947-4-1:20 18的一致性:在被保护开关器件的额定条件短路电流Iq下进行测试；短路测试与北美的协调；功能安全应用的可靠性数据（新附录K）；与电子电路和保护阻抗有关的安全方面（新附件N）；引入涵盖较高锁定转子电流影响的规定，以实现高效率等级；提及专用接线附件；控制电路在保持和拾取操作期间的功耗的定义和测量方法；负荷监测指标（新附录M）。
IEC 60947-6-2:2020 This document applies to control and protective switching devices (or equipment) (CPS), the main contacts of which are intended to be connected to circuits of rated voltage not exceeding 1 000 V AC or 1 500 V DC.
It covers control and protective switching device (CPS):
- which provides protective and control functions for circuits and motors;
- where its control function is operated exclusively otherwise than by hand;
- which provides continuity of service after over-current conditions; and
- which can have additional functions, such as isolation or communication.
This edition includes the following significant technical changes with respect to the previous edition:
- editorial changes according to ISO/IEC directives Part 2,
- alignments with IEC 60947-1:2020:
- markings ("s", "sol", "r" or "f");
- constructional requirements including material requirements;
- requirements for screwless terminals;
- measurement method of the pole impedance;
- EMC requirement and testing;
- procedure to determine data for electromechanical CPS’s used in functional safety applications;
- harmonisation with IEC 60947-2:2016:
- operation tests of under-voltage relays and shunt releases;
- CPS for IT systems (Annex G);
- coordination with other short-circuit protective devices;
- alignments with IEC 60947-4-1:2018:
- test at the rated conditional short-circuit current Iq of protected switching devices;
- short-circuit tests harmonisation with North America;
- reliability data for functional safety applications (new Annex K);
- safety aspects related to electronic circuits and protective impedance (new Annex N);
- introduction of provisions covering the impact of higher locked rotor current to achieve high efficiency class;
- mention of dedicated wiring accessories;
- definitions and measurement method of the power consumption of the control circuit during holding and pick-up operations;
- load monitoring indicators (new Annex M).
