Medium Voltage Fuses

2,400 - 38,000 VAC • Current-Limiting

Current-limiting “E” and “R” rated fuses

are equipped with a mechanical indicator

or striker pin that protrudes through the

fuse cap upon operation of the fuse. This

provides visual identification of a blown

fuse and can be used as a trigger for

external devices.

Note: Extension distance ¹/₂” min; extension

force 2lb. min

General Information

The terms “Medium Voltage” and “High Voltage” have been used

interchangeably by many people to describe fuses operating above 600

volts. Technically speaking, “medium voltage” fuses are those intended

for the voltage range from 2,400 to 38,000 VAC. “High voltage” fuses

are for circuits carrying voltages greater than 38,000 VAC.

“E” rated fuses are considered to be general purpose fuses and can be

used to protect against low and high values of fault current. “R” rated

fuses are designed for back-up protection. They must be used in series

with other devices such as motor overload relays in order to achieve

both overload and short-circuit protection.

Medium voltage fuses are not intended to provide overload protection in

the same sense as fuses rated 600 volts or less. Medium voltage fuse

current ratings do not have the same meanings as the ampere ratings of

low voltage fuses.

Littelfuse now offers a complete selection of “E” and “R” rated

medium voltage fuses for the protection of transformers, potential

transformers, feeders, and motor circuits. Single, double, and triple

barrel designs are available to cover a wide range of current, voltage,

and interrupting ratings. Conventional ferrule type, clip lock, and bolt-in

mounting configurations are now available for virtually any application.

Hermetically sealed fuses for use in hazardous environments are also

offered.

All medium voltage fuses are limited in their ability to interrupt low value

overcurrents, especially those between 100% and 200% of the fuse’s

continuous current rating. They are designed to carry their rated current

without exceeding the temperature rise permitted by NEMA and ANSI

standards.

Additional application data can be found in the Fuse Application section

of this catalog.

Contact the factory or your local Littelfuse representative for additional

fuse ratings or custom mounting configurations.
