45、edition of UL 60947-5-1. This standard is based on IEC 60947-5-1, Edition 3. This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Industrial Control Equipment, of the Council on the Harmonizat

46、ion of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This standard was reviewed by the CSA Integrated Committee on Industrial Control, un

47、der the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved as a National Standard of Canada by the Standards

48、Council of Canada (SCC). This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Application of Standard Where reference is made to a specic number of samples to be tested, the specied number is considered a minimum quantity. Note: Althou

49、gh the intended primary application of this Standard is stated in its scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. This CAN/CSA-C22.2 No. 60947-5-1, Standard for Safety for Low-Voltage Switchgear and Controlgear Part 5-1: Control Circuit Devices and Switching Elements Electromechanical Control Circuit Devices, is to be used in conj
