家用和类似用途不带集成过流保护的便携式剩余电流装置 (PRCD

[中文适用范围]： IEC 61540:2023 适用于家用和类似用途的便携式剩余电流装置 (PRCD)，由插头、剩余电流装置 (RCD) 和一个或多个插座或连接装置组成。它们不包含过流保护。它们适用于单相和两相系统，额定电流不超过 16 A，额定电压不超过 250 V AC，或额定电流不超过 32 A，额定电压不超过 130 V AC 对地。除了固定装置为下游电路提供的保护之外，它们还旨在提供直接接触时防止电击危险的保护。第二版取消并取代了 1997 年发布的第一版及其修正案 1:1998。此版本构成技术修订。相对于前一版本，此版本包括以下重大技术更改： a) 文档内容进行了修订并与 IEC 60755（剩余电流设备团体安全出版物）和标准库“块和模块”保持一致。 b) 引入分类“4.3 根据线路电压故障时自动断开后的行为”。 c) 增加了新的要求和测试，以涵盖引入的防电击危险保护功能： - 在缺少保护导体的情况下验证正确的性能。 - 在存在危险带电保护导体的情况下验证正确性能。 - 验证在失去保护导体的情况下的正确性能。 - 验证保护导体中出现外部故障电流时的行为。 d) 根据 IEC 62752 (IC-CPD) 修订和修改了电气间隙/爬电距离。 e) 修订最小工作电压值。 f) 引入-25℃至+40℃之间环境空气温度的要求和测试。 g) 介电性能测试经过修订并与标准库“块和模块”保持一致。 h) 符合 IEC 62752 (IC-CPD) 的相关条款； IC-CPD 是描述类似产品/功能的产品标准。 i) 所有附件均根据主文件的内容进行了修订和调整。 [外文原描述]： IEC 61540:2023 applies to portable residual current devices (PRCDs) for household and similar uses, consisting of a plug, a residual current device (RCD) and one or more socket-outlets or a provision for connection. They do not incorporate overcurrent protection. They are intended for single- and two-phase systems for rated currents not exceeding 16 A for rated voltages not exceeding 250 V AC, or for rated current not exceeding 32 A for rated voltages not exceeding 130 V AC to earth. They are intended to provide protection against shock hazard in case of direct contact, in addition to the protection provided by the fixed installations for the circuit downstream. This second edition cancels and replaces the first edition published in 1997 and its Amendment 1:1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The content of the document was revised and aligned with IEC 60755 (group safety publication for residual current devices) and standard library "blocks and modules". b) Introduction of classification "4.3 According to behaviour after opening automatically in case of failure of the line voltage". c) New requirements and tests were added to cover the introduced protection function against shock hazard: - Verification of correct performance in the case of missing protective conductor. - Verification of correct performance in the case of hazardous live protective conductor. - Verification of correct performance in the case of loss of protective conductor. - Verification of behaviour in the case of external fault current in the protective conductor. d) Clearances/creepage distances revised and modified in alignment with IEC 62752 (IC‑CPD). e) Revision of values for minimum operating voltages. f) Introduction of requirements and test for ambient air temperature between −25 °C and +40 °C. g) Test of dielectric properties revised and aligned with standard library "blocks and modules". h) Relevant clauses aligned with IEC 62752 (IC-CPD); IC-CPD is a product standard describing similar product/features. i) All annexes revised and adapted to content of main document.
