CSA C22.2 NO. 248.13:22

Description

Preface This is the harmonized ANCE, CSA Group, and UL Standard for Low-Voltage Fuses – Part 13: Semiconductor Fuses . It is the second edition of NMX-J-009/248/13-ANCE, third edition of CSA C22.2 No. 248.13, and the third edition of UL 248-13. This edition of NMX-J-009/248/13-ANCE supersedes the first edition published in 2000. This edition of CSA C22.2 No. 248.13 supersedes the second edition published in 2000. This edition of UL 248-13 supersedes the second edition published in 2000. This harmonized standard was prepared by the Association of Standardization and Certification, (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). 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 This Part is intended to be read together with the Standard for Low-Voltage Fuses – Part 1: General Requirements, hereafter referred to as Part 1. The titles of the Clauses in this Part correspond to the similarly titled Clauses in Part 1. The requirements of Part 1 apply unless modified by this Part. For the Part 1 requirements, refer to the Standard for Low-Voltage Fuses – Part 1: General Requirements, NMX-J-009-248/1-ANCE / CSA C22.2 No. 248.1 / UL 248-1. 1.2 This Part applies to semiconductor fuses rated 2000 Vac or less. DC ratings are optional. NOTE: CSA C22.1, Canadian Electrical Code, Part I, defines low voltage as any voltage exceeding 30 V but not exceeding 1000 V inclusive and high voltage as any voltage exceeding 1000 V. The National Electrical Code, NFPA 70, defines high voltage as more than 600 V, nominal.
