POWER FUSES

For over 60 years, Eaton has been the World Leader in the design and manufacture of medium voltage power fuses. As the only full-line manufacturer of both current limiting and expulsion fuses, Cutler-Hammer fuses meet the needs of every medium voltage application for the protection of voltage systems from 2.4 kV through 145 kV. A better understanding of some fuse terminology will help you understand and select the correct fuse. The following is a brief overview of those terms.

Power or Distribution?
The differentiation is intended to indicate the test conditions and where fuses are normally applied on a power system, based on specific requirements for generating sources, substations and distribution lines. Each class has its unique set of voltage, current and construction requirements.

See ANSI C37.42, .44, .46 and .47
