Medium Voltage Fuses 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 Medium Voltage Fuses 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. 24 Hour Emergency Service is available. Call 847 824 1188.

When properly applied, they can protect against high and low fault currents. Voltage Rating: 2,400 volts - 38,000 volts Current Range: 10E - 600E Options NEMAStandards for "E" rated medium voltage fuses require that fuses rated 100E or less open within 300 seconds (5 minutes) when subjected to an RMSvalue of 200-240% of the fuse continuous current rating; and fuses with an "E" rating larger than 100E must open within 600 seconds (10 minutes) when subjected to an RMS current of 220240% of the fuse's continuous current rating. These values establish one point on the time-current curve. *Hermetically sealed for use in hazardous locations (add "S" suffix to part number) * Clip-lock (CL) and bolt-in styles available.

KV Rated 9.75" Medium Voltage Fuses Since these fuses are used for the protection of general purpose circuits which may contain transformers, motors, and other equipment producing in-rush and/or overload currents, fuses should generally be rated at 140% of the normal full load current, and circuits should be analyzed to ensure that system load currents will not exceed the current rating of the fuse.
