Preface This is the harmonized ANCE, CSA, and UL standard for Low-Voltage Fuses - Part 1: General Requirements. It is the second edition of NMX-J-009/248/1-ANCE, the third edition of CSA C22.2 No. 248.1-11, and the third edition of UL 248-1. This edition of NMX-J-009-248/1-ANCE cancels the previous edition published in 2000. This edition of CSA C22.2 No. 248.1-11 supersedes the previous edition published in 2000. Scope 1.1.1 This Standard applies to low-voltage fuses rated 1000 V or less, AC and/or DC, with interrupting ratings up to 200 kA. These fuses are intended to be used in accordance with the Canadian Electrical Code, Part I (CEC), and the National Electrical Code, NFPA 70 (NEC). 1.2 Object 1.2.1 This Standard and its subsequent Parts establish the characteristics, construction, operating conditions, markings, and test conditions for each of the fuse classes so that initial investigation and follow-up verification can be performed in an orderly manner.
