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.

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.
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.
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.
Contact the factory or your local Littelfuse representative for
additional fuse ratings or custom mounting configurations.

R-RATED MEDIUM VOLTAGE FUSES
Description
R-rated fuses provide required short-circuit protection for
medium voltage motors, motor controllers and associated
circuitry. These components have limited ability to absorb the
energy of large short-circuit currents. Medium voltage motor
controllers contain overload relays which provide both overload
protection and locked rotor protection to the motor. The
controllers are also intended to interrupt low value short-circuits
within the capability of the motor controller. This protects the
medium voltage fuse from sustained overcurrents which are
less than their minimum interrupting rating.
NEMA Standards for R-rated medium voltage power fuses
require they operate within 15-35 seconds when subjected
to an rms current 100 times the R rating. For example, a
fuse with a 2R rating will open within 15 to 35 seconds on
an applied current of 2 x 100 = 200 amperes.

E-RATED MEDIUM VOLTAGE FUSES
Description
E-rated fuses have time current characteristics designed to
provide current-limiting protection for power transformers,
potential transformers, power centers, feeder centers, and
unit sub stations. When properly applied, they can protect
against high and low fault currents.
NEMA Standards for E-rated medium voltage fuses require
that fuses rated 100E or less open within 300 seconds
(5 minutes) when subjected to an RMS value 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 220-
240% of the fuse’s continuous current rating. These values
establish one point on the time-current curve.

• Clip-lock (CL) available.

Application Note
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.
