Low-voltage fuses — Part 19: Photovoltaic fuses (Trinational standard with UL 248-19 and NMX-J-009/248/19-ANCE)
Preface This is the harmonized ANCE, CSA Group, and ULSE Standard for Fuses – Part 19: Photovoltaic Fuses. It is the first edition of NMX-J-009/248/19-ANCE , the first edition of CAN/CSA-C22.2 No 248.19, and the first edition of UL 248-19. This harmonized standard has been jointly revised on November 25, 2024. For this purpose, CSA Group and UL are issuing revision pages dated November 25, 2024, and ANCE is issuing a new edition dated November 25, 2024. This harmonized standard was prepared by the Association of Standardization and Certification, (ANCE), CSA Group and ULSE Inc. (ULSE). The efforts and support of the Technical Harmonization Subcommittee, THC 32B under CANENA on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. The present Mexican standard was developed by the CT 32 “Fusibles” from the Comite de Normalizacion de la Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaboration of the manufacturers and users of fuses. This standard was reviewed by the CSA Subcommittee on Fuses and Fuseholders, 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. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Scope 1.1 This Part applies to fuses for photovoltaic (PV) systems rated up to 2000 Vdc. 1.2 Fuses for photovoltaic (PV) systems are intended to be used for the protection of photovoltaic strings or arrays and their associated wiring to provide protection against overloads or short circuits within the marked electrical ratings in accordance with the Canadian Electrical Code (CSA C22.1 Canadian Electrical Code Part I) in Canada, the Standard for Electrical Installations, NOM-001-SEDE, in Mexico and the National Electrical Code NEC), NFPA-70, in the United States of America. 1.3 These types of fuses are not intended to protect downstream inverter components, such as capacitors and against the discharge of such capacitors back into the arrays.
