Medium Voltage Fuses
ꢀ
2400 - 25,500 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 pro-
tection. 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 trans-
formers, 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 inter-
rupt 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 the POWR-GARD Products
catalog (PF101).
Contact the factory or your local Littelfuse representative for
additional fuse ratings or custom mounting configurations.
24 Hour Emergency Service is available.

FEATURES
CHARACTERISTICS
“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 over-
load protection and locked rotor protection to the motor. The
controllers are also intended to interrupt low value short cir-
cuits within the capability of the motor controller. This pro-
tects the medium voltage fuse from sustained overcurrents
which are less than their minimum interrupting rating.
Voltage Rating: 2,400 volts – 15,500 volts
Current Range: 2R – 36R
OPTIONS
ꢀ
Hermitically sealed for use in hazardous locations
(add “S” suffix to part number)
ꢀ
ꢀ
Hookeye attachment (add “W” suffix to part number)
Bolt-in mounting configurations
NEMA Standards for “R” rated medium voltage power fuses
require that they operate within 15-35 seconds when sub-
jected to an rms current 100 times the “R” rating. For exam-
ple, 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
Current Limiting
“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 value fault currents.
CHARACTERISTICS
Voltage Rating: 2,400 volts – 38,000 volts
Current Range: 10E – 600E
OPTIONS
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’s 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.
ꢀ
Hermetically Sealed for use in hazardous locations
(add “S” suffix to part number)
ꢀ
Clip-lock (CL) and bolt-in styles available.
Application Note:
Since these fuses are used for the protection of general
purpose circuits which may contain transformers, motors,
and other equipment producing inrush and/or overload cur-
rents, 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.

Clip Lock Design

The clip lock type designs ensures a positive contact between
the fuse and the connection cam. The fuse’s clip lock tab slides
in between the clip casting and the cam to prevent the fuse from
slipping or blowing out of the holder. This positive contact
improves heat dissipation and allows fuses to run cooler.

E Rated Potential Transformer Fuses
Current Limiting
Potential Transformer (PT) fuses are current limiting fuses
with high interrupting ratings designed for the protection of
potential transformers.
CHARACTERISTICS
Voltage Rating: 600VAC – 25,500 VAC
Current Range: 1/2E – 10E
Application Note:
When applying fuses for the protection of transformers,
the magnetizing current inrush must be considered. The
characteristics of the inrush, which can be matched with
a fuse’s time-current curve, should be available from the
transformer manufacturer.
