前言:这是CAN/CSA-E60730-2-10《家用和类似用途的电气自动控制-第2-10部分:电动机起动继电器的特殊要求》的第二版，采用了相同名称的IEC（国际电工委员会）标准60730-2-10（第二版，2006-10），但有加拿大的偏差。它取代了1994年出版的前一版CAN/CSA-E730-2-10《家用和类似用途的电气自动控制-第2部分:电动电动机起动继电器的特殊要求》（采用IEC 730-2-10:1991）。本标准拟与CAN/CSA-E60730-1:02《家用和类似用途的自动电气控制装置第1部分:一般要求》（采用IEC 60730-1:1999，加拿大偏差）结合使用。本标准适用于本标准规定范围内的合格评定。 范围和规范性参考第1部分的本条款适用，但以下情况除外:1.1替换:IEC 60730的本部分适用于与家用和类似用途设备相关的单相电机起动绕组的自动控制。本标准适用于使用NTC或PTC热敏电阻的电机起动继电器，其附加要求包含在附录J.1.1中。本标准适用于固有安全性、与设备安全相关的操作值、操作时间和操作顺序，以及用于或与设备安全相关的电机起动继电器的测试，家用或类似设备。非正常家用设备的电动机起动继电器，但可供公众使用，如商店、轻工业和农场的外行使用的设备，均在本标准的范围内。 本标准不适用于专为工业应用设计的电机起动继电器。在本标准中，“设备”一词是指“器具和设备”。“启动继电器”是指“电机启动继电器”。1.1.2本标准适用于包含电子设备的启动继电器，以及使用热敏电阻元件、热元件和磁性元件的启动继电器。1.1.3本标准不适用于通用继电器或IEC 60947系列1所涵盖类型的接触器和电动机起动器。本标准不适用于机械计时器或机械操作的电机起动装置。1.1.4本标准适用于与启动继电器电气和/或机械集成的手动控制装置。IEC 61058中包含了不构成起动继电器一部分的手动开关的要求- 1.

Preface This is the second edition of CAN/CSA-E60730-2-10, Automatic electrical controls for household and similar use - Part 2-10: Particular requirements for motor-starting relays, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60730-2-10 (second edition, 2006-10). It supersedes the previous edition published in 1994 as CAN/CSA-E730-2-10, Automatic electrical controls for household and similar use - Part 2: Particular requirements for electrically operated motor starting relays (adopted IEC 730-2-10:1991). This Standard is intended to be used in conjunction with CAN/CSA-E60730-1:02, Automatic electrical controls for household and similar use - Part 1: General requirements (adopted IEC 60730-1:1999, with Canadian deviations). This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.Scope and normative referencesThis clause of Part 1 is applicable except as follows: 1.1 Replacement: This part of IEC 60730 applies to controls for automatically controlling the starting windings of single phase motors associated with equipment for household and similar use. This standard applies to motor-starting relays using NTC or PTC thermistors, additional requirements for which are contained in Annex J. 1.1.1 This standard applies to the inherent safety, to the operating values, operating times and operating sequences where such are associated with equipment safety, and to the testing of motor-starting relays used in, or in association with, household or similar equipment. Motor-starting relays for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. This standard does not apply to motor-starting relays designed exclusively for industrial applications. Throughout this standard, the word "equipment" means "appliance and equipment". The words "starting relay" mean "motor-starting relay". 1.1.2 This standard applies to starting relays incorporating electronic devices and starting relays using thermistor elements, thermal elements and magnetic elements. 1.1.3 This standard does not apply to general purpose relays or to contactors and motor starters of the type covered by the IEC 60947 series1. This standard does not apply to mechanical timers or mechanically operated motor-starting devices. 1.1.4 This standard applies to manual controls when such are electrically and/or mechanically integral with starting relays. Requirements for manual switches not forming part of a starting relay are contained in IEC 61058-1.
