The C60 family of Multi 9™ circuit breakers meeting IEC 60947-2 is available primarily for equipment for export from the United States to countries requiring IEC Certification rather than UL Listing. Three types of IEC Rated C60 devices are available: C60N, C60H, and C60L circuit breakers. These model numbers refer to the maximum current interrupting (Ultimate Breaking Capacity) ratings. Each of these devices is available with several characteristic trip curve ratings, as listed in the tables with catalog numbers. They include devices ranging from 1 to 63 A. (For higher current ratings, select devices from the higher current C120 series).
