Description / Abstract:
This standard establishes specifications for high-voltage
(1000 V) distribution class current-limiting type fuses and
associated accessories. All of these devices are intended for use
on alternating current (ac) systems. These specifications apply to
the following specific types of equipment:
a) Distribution class current-limiting type fuses and fuse
units
b) Distribution class current-limiting fuse disconnecting
switches
c) Item a) and item b) used in fuse-enclosure packages
d) Fuse supports, fuse units, refill units, and fuse mountings
of the type intended for use with distribution class
current-limiting type fuses, and fuse disconnecting switches.
e) Disconnecting devices created by the use of a removable
switch blade in a distribution class current-limiting type fuse
support.
Purpose
Standard specifications for the devices covered by this document
are necessary to maintain consistent development and application of
these devices by manufacturers and users of these devices.
