低压开关设备、控制设备及其成套设备 信息交换用产品数据和特性 第1部分：目录数据

[中文适用范围]： 本部分 IEC 62683 建立了基于定义属性的低压开关设备和控制设备及其组件类别的一般描述参考字典。该字典用于促进描述低压开关设备和控制设备、其附件及其组件的数据的电子格式交换。本文件提供了数量有限且主要用于产品展示、选择和识别（特别是在电子目录中）的属性和类别的清晰且无歧义的定义。每个属性都有明确定义的含义和名称，并在相关情况下，有定义的值列表、定义格式和定义单位。制造商特有的功能不在本文件范围内。 [外文原描述]： IEC 62683-1:2026 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. IEC 62683-1:2026 establishes the reference dictionary of the general description of classes of low-voltage switchgear and controlgear and their assemblies based on defined properties. This dictionary is used to facilitate the exchange in electronic format of data describing low voltage switchgear and controlgear, their accessories and their assemblies. This document provides clear and unambiguous definitions of a limited number of properties and classes which are mainly used for presentation, selection and identification of products particularly in electronic catalogues. Each property has an unambiguously defined meaning and name, and where relevant, a defined value list, a defined format, and a defined unit. Manufacturer specific features are not covered. This second edition cancels and replaces the first edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition for reflecting the content of the IEC CDD 62683DB which has been updated with the change requests C00073, C00074, C00081, C00087, C00089, C00098, C00100, C00107, C00111, C00116, C00119, C00122, C00146, C00148, C00159, C00167, C00174 and C00135: a) New device class descriptions: ACC304, ACC305, ACC413, ACC417, ACC503, ACC504, ACC505, ACC512, ACC516, ACC536, ACC537, ACC538, ACC540, ACC541, ACC542, ACC543, ACC544, ACC545, ACC546, ACC547, ACC548. b) New associated properties. c) New assembly class structure: ACC101, ACC102, ACC103, ACC104, ACC106, ACC110, ACC111, ACC112, ACC113, ACC114, ACC115, ACC116, ACC117, ACC118, ACC119, ACC120, ACC121, ACC123, ACC124, ACC125, ACC126, ACC127, ACC131, ACC132, ACC133, ACC135, ACC141, ACC142, ACC143, ACC144, ACC145, ACC146, ACC147, ACC148, ACC150, ACC151, ACC152, ACC153, ACC154, ACC155, ACC156, ACC157, ACC158, ACC159, ACC160, ACC161, ACC162, ACC163, ACC164, ACC165, ACC166, ACC167, ACC170, ACC171, ACC172, ACC173, ACC174, ACC175.
