Fuseholders — Part 1: General requirements (Trinational standard with UL 4248-1 and NMX-J-009/4248/1-2022-ANCE)
Preface This is the harmonized ANCE, CSA Group, and ULSE standard for Fuseholders – Part 1: General Requirements . It is the third edition of NMX-J-009/4248/1-ANCE, the third edition of CSA C22.2 No. 4248.1, and the third edition of UL 4248-1. This harmonized standard has been jointly revised on June 18, 2025. For this purpose, CSA Group and ULSE are issuing revision pages dated June 18, 2025, and ANCE is issuing a new edition dated June 18, 2025. This harmonized standard was prepared by the Association of Standardization and Certification, (ANCE), CSA Group, and ULSE. The efforts and support of the Technical Harmonization Subcommittee, 32B, Fuses, Fuseholders, on the Harmonization 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. The present Mexican Standard was developed by the TC 32 Fuses from the Comite de Normalizacion de la Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaboration of the fuse manufacturers and users. This Standard was reviewed by the CSA Subcommittee on Fuses and Fuseholders and approved by the CSA Technical Committee on Industrial Products under the jurisdiction of the CSA Strategic Steering Committee on the Requirements for Electrical Safety. This standard has been developed in compliance with the Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 1.1 These fuseholders and devices accommodate fuses to be employed in electrical circuits and are intended to be used in accordance with the Canadian Electrical Code, Part I (CE Code Part I), CSA C22.1, the National Electrical Code, NFPA 70, or the Mexican Electrical Code, NOM-001. 1.2 These requirements cover: a) Fuseholders for fuses intended for use with fuse classes covered in the ANCE NMX-J-009-248; CSA C22.2 No. 248; and UL 248 series of standards, Parts 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15; and b) Fuseholder accessories (such as covers, indicators, adapters, etc.). 1.3 This Standard and its subsequent Parts establish the characteristics, construction, operating conditions, markings, and test conditions for fuseholders. 1.4 The titles of the Clauses in this Part 1 correspond to the similarly titled Clauses in the subsequent Parts.
