it has a advantage of current limiting featur…so its used for protection of contactors which may melt for higher value of current…you can see the autometic starter of motor has contactors.used for swiching..so fuse is connected in series with it..after 2 to 3 operation..there will no us of fuse…as it melts due to overheating…for 30 ka short circuit current..it limits to 10 ka current.s.c..which is the rating of contactors.
