家用和类似用途固定电气装置用开关.第1部分:一般要求

[中文适用范围]： 本部分 IEC 60669 适用于手动操作的通用功能开关，仅用于交流电(AC)，额定电压不超过 440V，额定电流不超过 63A，适用于家庭和类似固定电气装置，室内或室外均可使用。 对于带有无螺钉端子的开关，额定电流限制为 16A。 注1：正在考虑将范围扩展到额定电压高于 440V 的开关。根据附录 D，带有绝缘穿刺端子(IPT)的开关额定电流限制为 16A。 本文件涵盖的开关在正常使用时适用于控制以下所有负载： - 钨丝灯负载的电路； - 外部镇流灯负载的电路（如 LED、CFL、荧光灯负载）； - 自镇流灯负载的电路（如 LEDi 或 CFLi）； - 功率因数不低于 0.95 的基本电阻负载的电路； - 单相电动机负载的电路，额定电流不超过 3A（250V 或 750VA）和 4.5A（120V 或 540VA），功率因数不低于 0.6。 本文件还适用于开关盒，但不包括嵌入式开关的安装盒。 它还适用于以下类型的开关： - 带有指示灯的组合开关； - 电磁遥控开关； - 带有延时装置的开关； - 开关与其他功能的组合（不包括带熔断器的开关）； - 电子开关； - 带有柔性电缆出口和固定装置的开关； - 隔离开关； - 用于家庭和建筑电子系统的开关及相关配件； - 消防员开关。 符合本文件的开关适用于环境温度通常不超过 +25°C 至 +40°C，但在 24 小时内平均值不超过 +35°C，环境空气温度下限为 -5°C。 在特殊条件下（如船舶、车辆等）和危险场所（如可能发生爆炸的地方），可能需要特殊的结构和/或额外的要求。 本标准不包括对防止固体异物进入的开关的要求和测试。这些正在考虑中。 [外文原描述]： IEC 60669-1:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. This part of IEC 60669 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.
