medium voltage fuses 69 w w w . l i t t e l f u s e . c o m medium voltage fuses ? 2005 littelfuse ? powr-gard ? products catalog 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 fuses 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. 3"dia dim.a (clip center) 6.38" dim.b 9.75" aa d d d ddd figure 14 figure 15 figure 16 characteristics voltage rating: 2,400 volts C 38,000 volts current range: 10e C 600e options ? hermetically sealed for use in hazardous locations (add s suffix to part number) ? clip-lock (cl) and bolt-in styles available. e rated catalog number old catalog number size dim. a (inches) dim. b (inches) max interrupting rating rms (asym) figure number 2.75 max. kv 10e-1c-2.75 lcx 10e 10e 7" 10.875" 80,000 14 15e-1c-2.75 15e 7" 10.875" 80,000 14 20e-1c-2.75 20e 7" 10.875" 80,000 14 25e-1c-2.75 25e 7" 10.875" 80,000 14 30e-1c-2.75 lcx 30e 30e 7" 10.875" 80,000 14 40e-1c-2.75 lcx 40e 40e 7" 10.875" 80,000 14 50e-1c-2.75 lcx 50e 50e 7" 10.875" 80,000 14 65e-1c-2.75 lcx 65e 65e 7" 10.875" 80,000 14 80e-1c-2.75 lcx 80e 80e 7" 10.875" 80,000 14 100e-1c-2.75 lcx 100e 100e 7" 10.875" 80,000 14 125e-1c-2.75 125e 7" 10.875" 80,000 14 150e-1c-2.75 150e 7" 10.875" 80,000 14 200e-1c-2.75 200e 7" 10.875" 80,000 14 125e-2c-2.75 lcx 125e 125e 7" 10.875" 80,000 15 150e-2c-2.75 lcx 150e 150e 7" 10.875" 80,000 15 175e-2c-2.75 lcx 175e 175e 7" 10.875" 80,000 15 200e-2c-2.75 lcx 200e 200e 7" 10.875" 80,000 15 225e-2c-2.75 225e 7" 10.875" 80,000 15 250e-2c-2.75 lcx 250e 250e 7" 10.875" 80,000 15 300e-2c-2.75 lcx 300e 300e 7" 10.875" 80,000 15 350e-2c-2.75 350e 7" 10.875" 80,000 15 400e-2c-2.75 lcx 400e 400e 7" 10.875" 80,000 15 450e-2c-2.75 450e 7" 10.875" 80,000 15
