标准摘要
[中文适用范围]: 本部分 IEC 60669 适用于时间延迟开关(以下简称 TDS),其额定电压不超过 440 V AC,额定电流不超过 63 A,用于家庭和类似的固定电气装置,室内或室外,手动和/或远程控制操作。对于控制电路,额定控制电压不超过 440 V AC 或 220 V DC。 TDS 配备有时间延迟装置,通过机械、热、气动、液压或电气方式或其组合进行操作。 电子 TDS 在 IEC 60669-2-1 的范围内,但不在本文件的范围内。 仅包含被动元件(如电阻、电容、正温度系数(PTC)和负温度系数(NTC)元件以及印刷电路板的 TDS 不被视为电子 TDS。 对于带有无螺丝端子的开关,额定电流限制为 16 A。 本文件涵盖的开关适用于正常使用中控制以下所有负载的电路: - 钨丝灯负载电路; - 外部镇流灯负载电路(例如 LED、CFL、荧光灯负载); - 自镇流灯负载电路(例如 LEDi 或 CFLi); - 功率因数不低于 0.95 的基本电阻性负载电路; - 单相电机负载电路,额定电流在 250 V 时不超过 3 A(750 VA),在 120 V 时不超过 4.5 A(540 VA),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。 符合本文件的开关适用于环境温度通常不超过 +40°C 的场合,但在 24 小时内的平均值不超过 +35°C,环境空气温度的下限为 -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),可能需要特殊结构和/或附加要求。 [外文原描述]: IEC 60669-2-3:2024 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60669-2-3:2024 EXV includes the content of the references made to IEC 60669-1:2017. IEC 60669-2-3:2024 applies to time-delay switches (hereinafter referred to as TDS) with a rated voltage not exceeding 440 V AC and a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors, operated by hand and/or by remote control. For the control circuit, the rated control voltage does not exceed 440 V AC or 220 V DC. This fourth edition cancels and replaces the third edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Revision of the present edition with reference to IEC 60669-1:2017 (Edition 4); b) Introduction of a revision to Annex E "Additional requirements and tests for switches intended to be used at a temperature lower than −5 °C".
