  • SCOPE

    1.1 Scope

    This Part applies to semiconductor fuses rated 2000 V ac or less. DC ratings are optional.

    Note: The Canadian Electrical Code, Part I, defines low voltage as any voltage from 31 to 750 V inclusive and high voltage as any voltage above 750 V. The National Electrical Code, NFPA 70-1996 , Section 710-2 defines high voltage as more than 600 V, nominal.
