家用及类似用途机电式接触器

[中文适用范围]： 本文件适用于家用和类似用途的机电式空气断路接触器，其主触点用于连接额定电压不超过440V交流电（相间）的电路，额定工作电流不超过63A（使用类别AC-7a）或32A（使用类别AC-7b、AC-7c和AC-7d），额定条件短路电流不超过6kA。 本文件不适用于符合IEC 60947-4-1的接触器、半导体接触器、特殊应用设计的接触器以及接触器的辅助触点（这些内容在IEC 60947-5-1中处理）。 本文件规定了接触器的特性、符合条件（操作和行为、介电性能、外壳提供的防护等级、结构、电磁兼容特性）、测试方法和序列、样品数量以及接触器或制造商文献中应提供的信息。 [外文原描述]： IEC 61095:2023 applies to electromechanical air break contactors for household and similar purposes provided with main contacts intended to be connected to circuits the rated voltage of which does not exceed 440 V AC (between phases) with rated operational currents less than or equal to 63 A for utilization category AC-7a, and 32 A for utilization categories AC‑7b, AC‑7c and AC-7d (expressed in rated power), and rated conditional short-circuit current less than or equal to 6 kA. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of requirements for screwless terminals; b) addition of requirements for the switching of LED lamps. Contactors for domestic and similar applications can be used for controlling lighting loads which is increasingly using LED lamp technology. A specific category for contactors is created: AC-7d. Requirements and tests are added to cover this market development, mainly for making and breaking and conventional operational performance; c) addition of requirements for contactors with electronically controlled electromagnet. Household contactors with electronically controlled electromagnet are available for years on the market. To fully cover such device, requirements and tests are added, dealing mainly with operating limits, behaviour in abnormal conditions, breakdown of components, EMC tests, etc. d) embedded software. More and more contactors are incorporating electronic circuits with embedded software. A reference is provided to guide the design of the software.
