IEEE/ANSI C37.42-1996

This standard establishes specifications for high voltage (above 1000 volts) expulsion type distribution class fuses, cutouts, fuse disconnecting switches, fuse links and associated accessories. All of these devices are intended for use on alternating current distribution systems. These specifications apply to the following specific types of equipment: a) Open, enclosed, and open link types of fuses and cutouts. b) Open and enclosed fuse disconnecting switches. c) Fuse supports, fuse mountings and fuse hooks of the type used exclusively with distribution class fuses, cutouts, and fuse disconnecting switches. d) Removable switch blades of the type used exclusively with distribution class fuses, cutouts, and fuse disconnecting switches. e) Fuse links of the type used exclusively with distribution class fuses, cutouts, and fuse disconnecting switches. The fuses listed above are the same as those covered in IEC 282-2. The open and enclosed types of "distribution" class fuses and cutouts are the same as the class "A" fuses and cutouts covered in that document.
