WebWhen 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 ... http://www.electricalterminology.com/what-is-a-cartridge-fuse/

WebMedium voltage fuses offer a much wider range of system voltages, thereby resulting in a correspondingly large number of fuse voltage ratings. For questions, contact our Technical Support and Engineering Services Group at 800-TEC-FUSE (800-832-3873). WebSuch type of fuses are similar to back-up fuses in their design, with the difference that the number of fuse-elements connected in parallel is greater, which also increases the diameter of the fuses. The last group of the current-limiting fuses are the full-range fuse-links that are capable of breaking any current which can interrupt the fuse hungary jpg
