固定安装中用于永久连接的安装耦合器

[中文适用范围]： 本标准适用于额定电压不超过500V交流或直流、额定连接容量不超过10 mm²的两线至五线（含接地线）的固定安装永久性连接用安装耦合器。不适用于带有除电源电压以外额外触点的安装耦合器。安装耦合器由安装母连接器（插座侧）和安装公连接器（负载侧）组成，配备保持装置，用于永久性连接，不设计用于在负载下连接或断开，也不设计用于在首次安装、布线系统重新配置或维护期间进行连接或断开之外的操作。这意味着安装耦合器仅设计用于不频繁使用。符合本标准的安装耦合器适用于环境温度通常不超过+40°C（周期平均值不超过+35°C），且环境温度下限为-5°C的室内或室外使用场所。 [外文原描述]： IEC 61535:2019 applies to two-wire, up to five-wire installation couplers, including earth, if provided, with a rated voltage up to and including 500 V AC or DC and a rated connecting capacity up to and including 10 mm2 for permanent connection in electrical installations. Installation couplers with additional contacts for voltages other than mains voltages are outside the scope of this document. This second edition cancels and replaces the first edition published in 2009 and Amendment 1:2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - enlargement of the scope to DC application; - addition of further requirements as regards DC application (marking, etc.), no additional test procedures were deemed necessary; however some modifications were necessary in the normative text; - changes and enhancement of the field of application of installation couplers into outdoor applications; - addition of a suitable temperature range; - updating of the list of normative references, modified to undated references, where possible.
