37、THER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the harmonized ANCE, CSA Group, and UL Standard for medium-voltage ac contactors, controllers, and control centres. It is the second edition of NMX-J-564/106-ANCE, the second edition of CSA C22.2 No. 253, and the sixth edit

38、ion of UL 347. This edition of CSA C22.2 No. 253 supersedes the previous edition published in 2009. This edition of UL 347 supersedes the previous edition published on November 10, 2009. This harmonized Standard was prepared by the Association of Standardization and Certication, CSA Group and Underw

39、riters Laboratories Inc. The efforts and support of the medium-voltage control manufacturing industry and the CANENA Technical Harmonization Subcommittee THSC TC17 WG1 Medium Voltage Controllers, which includes representatives of UL, CSA Group, ANCE, and North American medium voltage control manufac

40、turers, are gratefully acknowledged. The present Mexican Standard was developed by the CT GTD Generacin, Transmisin y Distribucin from the Comit de Normalizacin de la Asociacin de Normalizacin y Certicacin, A.C., CONANCE, with the collaboration of the medium-voltage controller manufacturers and user

41、s. This Standard is considered suitable for use for conformity assessment within the stated scope of the standard. This Standard was reviewed by the CSA Task Force on Medium Voltage Controllers, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steeri

42、ng Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Note: Although the intended primary application of this Standard is

43、 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. Level of harmonization This Standard was prepared by comparing UL 347, existing CSA Group standards, and ANCE and IEC 60470-2000 requir

44、ements. These requirements were reviewed, compared, and, where possible, harmonized. Where harmonization was not possible due to local installation codes, the differing requirements are noted in the text of the document. When conicts between existing North American and IEC practices existed, the pra

45、ctice in North America is retained. This Standard is published as an equivalent standard for ANCE, CSA Group, and UL. An equivalent standard is a standard that is substantially the same in technical content except for national differences resulting from conicts in codes and governmental regulations.

46、 Presentation is word for word except for editorial changes. Formatting This Standard is formatted to facilitate comparison to IEC 60470 requirements, and to IEC 60694, which is the common clauses document to which IEC 60470 is subservient. Requirements are categorized and arranged in the clause num

47、bering structure currently used for IEC 60470. Where the requirements in this Standard are equivalent to those in IEC 60470, the subclause is assigned the equivalent IEC subclause number. Where this Standard does not include a subclause equivalent to those in IEC 60470, the entry JANUARY 29, 2016 NM

48、X-J-564/106-ANCE CSA C22.2 NO. 253-16 UL 347 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Vacant is shown for the IEC 60470 subclause number. Where this Standard includes a requirement not shown in IEC 60470, the subclause is assigned a

49、number of a higher numerical value than those used in the IEC document. In order to simplify the cross-referencing of corresponding requirements, the following clause numbering system is used: The clauses follow the IEC 60470 (and IEC 60694) format for clauses 1 through 7. Subclauses numbered .1 through .99 (but not subdivisions, e.g., those numbered .1.1, .1.2, .1.3, etc.) correspond to subclauses in IEC 60470 (and IEC 60694). Su
