家用和类似的固定电气设施用开关.第1部分:一般要求

[中文适用范围]： IEC 60669的本部分适用于手动操作的通用功能开关@仅适用于额定电压不超过440 V、额定电流不超过63 A的交流电(AC)@用于家用和类似固定电气装置@室内或室外户外。对于配备无螺钉端子@的开关，额定电流限制为 16 A。 注 1：根据附录 D，配备绝缘刺穿端子 (IPT??s) 的开关的额定电流限制为 16 A。本文件涵盖的开关为b 适用时@ 用于控制正常使用以下所有负载： ?C 用于钨丝灯负载的电路； ?C 用于外部镇流灯负载的电路（例如LED@CFL@荧光灯负载）； ?C 自镇流灯负载电路（例如 LEDi 或 CFLi）； ?C 功率因数不小于0@95的实质阻性负载的电路； ?C 电机负载的单相电路，250V（750VA）时额定电流不超过3A，120V（540VA）时额定电流不超过4@5A，功率因数不小于0@6。这适用于额定值不低于 10 A 且未经过附加测试的开关，以及额定值不低于 6 A 且未经过附加测试的瞬时开关。注 2：在以下国家，应测试用于控制电机浪涌电流的开关的适用性：AU。本文件也适用于开关@的盒子，但嵌入式开关的安装盒除外。注 3：IEC 60670-1 中给出了嵌入式开关盒的一般要求。它还适用于开关，例如带有指示灯的 ?C 开关； ?C电磁遥控开关（具体要求在IEC 606692-2中给出）；带有延时装置的C开关（IEC 60669-2-3中给出了特殊要求）； ?C 开关与其他功能的组合（与熔断器组合的开关除外）； ?C电子开关（具体要求在IEC 60669-2-1中给出）；具有软电缆引出和固定设施的C开关（见附件A）； ?C 隔离开关（特殊要求在IEC 60669-2-4中给出）；用于家庭和楼宇电子系统的C开关及相关配件（IEC 60669-2-5中给出了特殊要求）； ?C 消防员开关（IEC 60669-2-6 中给出了特殊要求）。符合本文件的开关适合在通常不超过 +40℃ 的环境温度下使用。但 24 小时内的平均值不超过 +35 ??周围空气温度下限为℃5℃注4：对于较低温度，请参见附录E。符合本文件的开关仅适合以周围环境温度不太可能超过+35℃的方式和地方安装在设备中。在存在特殊条件的场所@例如船舶@车辆等以及危险场所@例如容易发生爆炸的地方@可能需要特殊结构和/或附加要求 [外文原描述]： IEC 60669-1:2017 applies to manually operated general purpose functional switches, for alternating current (AC) only with a rated voltage not exceeding 440 V with a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors. For switches provided with screwless terminals, the rated current is limited to 16 A. This fourth edition cancels and replaces the third edition published in 1998, Amendment 1:1999 and Amendment 2:2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) change of the scope for motor load switches; b) deletion of some dated normative references; c) changes to the definitions; d) in Clause 5 the number of specimens to be used for the tests are clearly given in Table 1 (Corresponding Annex A of IEC 60669-1:1998 was therefore deleted); e) in Clause 5 it was clarified on which switches the tests of Clause 19 shall be carried out; f) requirements concerning 13 A switches have been included; g) mandatory indication that a terminal is suitable for rigid conductor only; h) requirements and test conditions for flexible conductors have been included in Clause 12; i) requirements for pilot light units have been included; j) new test for self-ballasted lamp loads in 19.3; k) Table 20 has been completely redrawn to cover normal, mini and micro-gap switches and renumbered Table 21; l) new informative Annex B including changes planned for the future in order to align IEC 60669-1 with the requirements of IEC 60998 (all parts), IEC 60999 (all parts) and IEC 60228; m) new informative Annex C about the circuit development for 19.3; n) new informative Annex D including additional requirements for insulation-piercing terminals; o) new informative Annex E including additional requirements and tests for switches intended to be used at a temperature lower than -5 °C.
