• Description: Medium Voltage Fuses
• Manufacturer: LITTELFUSE [Littelfuse]

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.
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.
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.
