This standard specifies design test requirements for high-voltage (above 1000 V) fuses, distribution enclosed single-pole air switches, fuse disconnecting switches, and accessories for use on alternating-current distribution systems. The devices to which this standard applies are as follows:

a) Distribution and power class expulsion type fuses

b) Distribution and power class current-limiting type fuses

c) Distribution and power class fuse disconnecting switches

d) Item a) through item c) used in fuse enclosure packages (see types listed in 1.2 and 1.3)

e) Fuse supports, fuse mountings, and fuse hooks of the type intended for use with distribution and power class fuses, and fuse disconnecting switches

f) Removable switch blades of the type used exclusively with distribution class oil cutouts, power class fuses, and distribution class fuse disconnecting switches

g) Fuse links when used exclusively with distribution class oil cutouts, power class fuses, and distribution class fuse disconnecting switches

h) Distribution class oil cutouts

i) Distribution class enclosed single-pole air switches

j) Distribution and power classes of expulsion, current-limiting, and combination external capacitor type fuses used with a capacitor unit, groups of units, or capacitor banks.

The distribution and power class expulsion type fuses listed previously in item a) through item j) are the same as those covered in IEC 60282-2 (1995-09)1. The distribution class expulsion type fuses are the same as the IEC 60282-2 class “A” fuses, and the power class fuses are the same as the IEC 60282-2 class “B” fuses. At present, IEEE standards do not cover the class “C” fuses listed in IEC 60282-2 (1995-09). Some of the current-limiting type fuses listed above are the same as those covered in IEC 60282-1 (1994-12). IEEE Std C37.41-2000 contains specific requirements for more types of current-limiting fuses than are covered in IEC 60282-1 (1994-12). Use caution if devices specified and tested per ANSI/IEEE standards are compared to those specified and tested per IEC standards, as they may or may not be the same.
