    This standard establishes specifications for high voltage (above 1000 volts) expulsion and current-limiting type power class fuses, and accessories. All of these devices are intended for use on alternating current systems. These specifications apply to the following specific types of equipment: a) Expulsion type power class fuses b) Current-limiting type power class fuses c) Power class fuse disconnecting switches d) Expulsion and current-limiting type, indoor power class fuses, items (a) through (c), used in fuse enclosure packages (FEP) e) Fuse supports, fuseholders, fuse hooks, fuse units, and refill units, of the type used exclusively with power class fuses and fuse disconnecting switches f) Removable switch blades of the type used exclusively with power class fuses and fuse disconnecting switches g) Fuse links of the type used exclusively with power class fuses and fuse disconnecting switches. The power class expulsion fuses listed above are similar to those now covered in IEC 60282-2. These power class expulsion fuses are similar to their class "B" fuses. At present, ANSI/IEEE standards do not cover the class "C" fuses listed in the IEC standard. Some of the power class current-limiting type fuses listed above are similar to those now covered in IEC 60282-1. This ANSI standard contains specific requirements for more types of current-limiting fuses than IEC 60282-1. View full abstract»
