标准摘要
[中文适用范围]： 本文件规定了主要用于工业或类似用途的端子排的要求，这些端子排具有 screw 型或 screwless 型夹紧单元，并应固定在支撑件上以提供电气和机械连接。本文件可用于铝导体之间或铝导体与铜导体之间的连接端子排。它适用于 intended 用于连接圆形导体的端子排（无论是否经过特殊制备），其横截面积在 2.5 mm² 至 300 mm²（AWG 12 至 600 kcmil）之间，并 intended 用于额定电压不超过 1000 V AC（高达 1000 Hz）或 1500 V DC 的电路。本文件可用作资格认证的指南，用于不符合 IEC 60228 的铝导体（例如，小于 10 mm²，柔性或其他材料）的端子排。本文件也可用作资格认证其他类型端子排的指南，用于除过线型端子排以外的铝导体（例如，部分绝缘端子排）。 [外文原描述]： IEC TS 60947-7-5:2021 specifies requirements for terminal blocks with screw-type or screwless-type clamping units primarily intended for industrial or similar use and to be fixed to a support to provide electrical and mechanical connection. This document can be used for terminal blocks for connection between aluminium conductors or aluminium to copper conductors. It applies to terminal blocks intended to connect round conductors, with or without special preparation, having a cross-section between 2,5 mm2 and 300 mm2 (AWG 12 to 600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1 000 V AC (up to 1 000 Hz) or 1 500 V DC.
