Medium Voltage Fuses  
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.  
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 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 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.
