125E1C8.25 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, E-rated fuses 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.Options

• Hermetically sealed for use in hazardous locations (add 'S' suffix to part number)
• Clip-lock (CL) available

Live PartsLive parts and mounting clips are available for mounting E-rated single, double, and triple barrel fuses. Note, all clips are sold in pairs.
