IEEE Std C37.42-2009 PDF

Scope: This standard establishes specifications for high-voltage (above 1000 V) expulsion-type distribution-class fuses, fuse cutouts, fuse disconnecting switches, their associated fuse links and disconnecting cutouts, and accessories for these devices. 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 and enclosed types of fuses and fuse cutouts b) Open and enclosed fuse disconnecting switches c) Fuse links of the type used exclusively with distribution-class fuses, fuse cutouts, and fuse disconnecting switches d) Open-link types of fuses, cutouts, and their associated fuse links e) Open and enclosed types of disconnecting cutouts f) Fuse supports, fuse mountings and fuse hooks of the type used exclusively with distribution-class fuses, fuse cutouts, fuse disconnecting switches, and disconnecting cutouts g) Fuseholders and removable switch blades of the type used exclusively with distribution-class fuse supports h) Mounting brackets used for distribution-class equipment and other accessories
