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:

Based on user experience and feedback, this new edition was proposed to revise existing general requirement for fuses and align Canadian requirements with those of our harmonized partners from USA & Mexico.
