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 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.
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.
