POWR-GARD^®Fuses—MediumVoltage

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 ¹2” minimum;

extension force 2 lb. minimum.

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.

Description

Littelfuse^®offers a 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 available for virtually

any application. Hermetically sealed fuses for use in hazardous

environments are also offered.

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.

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.

Contact the factory or your local Littelfuse representative for

additional fuse ratings or custom mounting conﬁgurations.

24-Hour Emergency Service is available. Call 800-227-0029,
