Preface This is the harmonized CSA Group, ECIA, and ULSE Standard for Electromechanical Elementary Relays – Part 1: General and Safety Requirements . It is the first edition of CSA C22.2 No. 61810-1, and the second edition of UL 61810-1. This harmonized standard is based on IEC Publication 61810-1: Edition 4.1, Electromechanical Elementary Relays – Part 1: General and Safety Requirements, issued November 2019. IEC 61810-1 is copyrighted by the IEC. This harmonized standard was prepared by CSA Group, ECIA, and ULSE. The efforts and support of the International Harmonization Committee (IHC) for the adoption of the IEC series of standards for Electromechanical Elementary Relays, 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, under 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 developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This part of IEC 61810 applies to electromechanical elementary relays (non-specified time all-or-nothing relays) for incorporation into low voltage equipment (circuits up to 1000 V alternate current or 1 500 V direct current). It defines the basic functional and safety requirements and safety-related aspects for applications in all areas of electrical engineering or electronics, such as: • general industrial equipment, • electrical facilities, • electrical machines, • electrical appliances for household and similar use, • information technology and business equipment, • building automation equipment, • automation equipment, • electrical installation equipment, • medical equipment, • control equipment, • telecommunications, • vehicles, • transportation (e.g. railways). Compliance with the requirements of this standard is verified by the type tests indicated. In case the application of a relay determines additional requirements exceeding those specified in this standard, the relay should be assessed in line with this application in accordance with the relevant IEC standard(s) (e.g. IEC 60730-1, IEC 60335-1, IEC 60950-1). 1DV.1 D2 Modification to Clause 1 by adding the following: 1DV.1.1 In Canada, this Standard applies to the safety of such equipment designed and constructed for installation and use in accordance with CSA C22.1, Canadian Electrical Code, Part I. 1DV.1.2 In Canada, general requirements applicable to this standard are provided in CSA C22.2 No. 0.
