1 SERIES E-RATED/MEDIUM VOLTAGE FUSES 5kV, 8kV and 15.5kV FERRULE MOUNTED FUSES Amp-trap E-rated 5kV 8kV and 15kV fuses have 2 or 3 inch diameter barrels with ferrules and are mounted in spring reinforced clips. They are UL listed as general purpose current-limiting fuses and are for use indoors (or outdoors in a weatherproof enclosure). The unique time-current characteristic of Ferraz Shawmut E-rated fuses allows them to be closely sized to transformer full-load rated current, as recommended by IEEE guidelines, without being affected by normal magnetizing inrush current. fuses are typically sized at transformer rated current of 133%, thereby providing superior overall protection. HIGHLIGHTS: E-Rated UL Listed 5.5kV and15.5kv Complies with ANSI C37.46 APPLICATIONS: Protection for 5.5, 8.25 or 15.5kV transformers or distribution system. Features/ Benefits UL Listed for compatiblity with UL listed equipment Ferrule mounting for standard clips and interchangeability with other brands of fuses Current Limiting for superior equipment protection Blown-fuse indicator gives positive identification of open fuse Non-venting for silent operation Metal Embossed Catalog Number and manufacturing date for lasting identification DEFINITIONS: E-rating E-rated fuses operate as follows: 100E or less - must melt in 300 seconds (5 mins.) at 200 to 240% of E (ampere) rating. Over 100E - must melt in 600 seconds (10 mins.) at 220 to 264% of E (ampere) rating. Example - A 100E fuse must melt in 300 seconds with an applied current of 200 to 240 amperes. General Purpose Current-Limiting Fuse A general purpose current-limiting power fuse is one that is capable of interrupting all currents from its rated interrupting rating down to the current that causes melting of the fusible element in one hour.
