40、echanical contactors and motor-starters. It is the secondedition of NMX-J-290-ANCE, the first edition of CAN/CSA C22.2 No. 60947-4-1, and the second editionof UL 60947-4-1A. This edition of UL 60947-4-1A supersedes the previous edition of UL 60947-4-1published on April 20, 2004.This standard is base
41、d on IEC Publication 60947-4-1: Edition 2 (2000), Low-voltage Switchgear andControlgear Part 4-1: Contactors and motor-starters Electromechanical contactors and motor-starters,as revised by the corrigendum (July 2001). IEC publication 60947-4-1 is copyrighted by the IEC.This second edition of UL 609
42、47-4-1A is being issued as a tri-national standard. A suffix “A” has beenadded to the existing standard number to identify it as such from the previously published UL/IEC-basededition. This edition of UL 60947-4-1A is the same standard edition number as the corresponding IECstandard with which this
43、standard is harmonized.This UL Standard, 60947-4-1A, Standard for Safety for Low-Voltage Switchgear and Controlgear Part4-1: Contactors and motor-starters Electromechanical contactors and motor-starters, is to be used inconjunction with the third edition of UL 60947-1. The requirements for contactor
44、s and motor-starters arecontained in this part 2 Standard and UL 60947-1.Requirements of this part 2 Standard, where stated, amend the requirements of UL 60947-1.This common standard was prepared by the Association of Standardization and Certification (ANCE), theCanadian Standards Association (CSA),
45、 and Underwriters Laboratories Inc. (UL). The efforts and supportof the Technical Harmonization Committee for Industrial Control Equipment, of the Council on theHarmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefullyacknowledged.This standard is considered
46、 suitable for use for conformity assessment within the stated scope of thestandard.This standard was reviewed by the CSA Subcommittee on 60947-4-1, under the jurisdiction of the CSATechnical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirementsfor Electrical Safet
47、y, and has been formally approved by the CSA Technical Committee.This standard has been approved as a National Standard of Canada by the Standards Council of Canada.This standard has been approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Where reference is
48、made to a specific number of samples to be tested, the specified number is to beconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remainsthe responsibility of the users of the standard to judge its s
