Current-Limiting Fuse Applications in Cement Plants

The characteristics of current-limiting fuses are examined for their application in electrical distribution systems in cement plants. The characteristics covered in this paper include: current-limiting effects, fuse classes, and fuse ratings as established by NEMA and UL, Inc. The current-limiting capability of today's modern fuses is examined in its application to system component protection. The withstand rating of various components of an electrical distribution system is examined to determine acceptable values of thermal energies and magnetic forces occurring during short-circuit conditions.
