e amp-trap ? cs-3 series e-rated / medium voltage fuses e 5 k v, 8 k v and 15.5 k v f errule mou n ted fuses amp-trap ? cs-3 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. cs-3 fuses are typically sized at transformer rated current of 133%, thereby providing superior overall protection. applications: protection for 5.5, 8.25 or 15.5kv transformers or distribution system. ? ? highlights: e-rated ul listed 5.5kv and15.5kv complies with ansi c37.46 ? ? ? d efi n itio n s : 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 inter - rupting rating down to the current that causes melting of the fusible element in one hour. a055f ac: 5e to 450e 5.5kv, 63ka i.r. sym. a825x ac: 10e to 200e 8.25kv, 50ka i.r. sym. a155f ac: 5e to 200e 15.5kv, 50ka i.r. sym. ? ? ? ratings ul listed to jeeg, fuses over 600 volts ul file # e143362 ? approvals spring-reinforced clips for cs-3 fuses: 228-700-530 (one pair of clips) for 3 diameter, 2 barrels max. feature s / 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 n on-venting for silent operation metal embossed catalog number and manufacturing date for lasting identification ? ? ? ? ? ?
