Low-voltage fuses — Part 1: General requirements
Scope:
1.1
This Standard applies to low-voltage fuses rated 1000 V or less, AC and/or DC, with interrupting ratings up to 300 kA (200 kA for Mexico). These fuses are intended to be used in accordance with the Canadian Electrical Code, Part I, CSA C22.1, NOM – 001, Mexican Electrical Code, and the National Electrical Code, NFPA 70.
1.2
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. The titles of the Clauses in this Part 1 correspond to the similarly titled Clauses in subsequent Parts.
Project need:
To maintain alignment with North American requirements and support innovation in the field of low voltage fuses by providing requirements for the construction in the Canadian context.
This proposed amendment is being developed at the request of manufacturers, certification bodies, and the CANENA Technical Harmonization Committee 32B. It will provide the industry with the latest general requirement for fuses. These requirements are intended for use in parallel with other requirement for specific classes of fuses as described in other Tri-national documents within the CSA-C22.2 No. 248 series standards.
