Full Description

Scope

This standard specifies design test requirements for high-voltage (above 1000 V) fuses, distributionenclosed single-pole air switches, disconnecting cutouts, fuse disconnecting switches, and accessories for use on ac power and distribution systems. Devices with rated maximum voltages to 170 kV are covered.The devices to which this standard applies are as follows:a) Distribution and power class expulsion type fusesb) Distribution and power class current-limiting type fusesc) Distribution and power class fuse disconnecting switchesd) Item a) through item c) used in fuse enclosure packagese) Fuse supports of the type intended for use with distribution and power class fuses, and fusedisconnecting switchesf) Fuse and disconnecting cutoutsg) Disconnecting devices created by the use of a removable switch blade in a distribution or powerclass fuse supporth) Distribution class enclosed single-pole air switchesi) Distribution class and power class expulsion, current-limiting, and combination types ofexternal capacitor fuses used with a capacitor unit, groups of units, or capacitor banksj) Backup current-limiting fuses ( motor-starter fuses ) used in conjunction with high-voltageClass E2 motor starters (see ANSI/UL 347-2000 [B1])1k) Fuse links when used exclusively with distribution class and power class fuses, and distributionclass and power class fuse disconnecting switchesl) Item a) through item d) and item f) through item i) having integral load-break means

Purpose

This standard specifies the minimum testing requirements for fuses and related devices. Suchstandardization is needed to ensure uniform minimum product testing for devices within the documentscope. Test areas covered are based on historical experience.

Abstract

Revision Standard - Inactive - Superseded.Required procedures for performing design tests for high-voltage distribution class and power class fuses, as well as for fuse-disconnecting switches and enclosed single-pole air switches, are specified. These design tests, as appropriate to a particular device, include the following test types: dielectric, interrupting, load-break, radio-influence, short-time current, temperature rise, time-current, manual operation, thermal-cycle, bolt torque, and liquid tightness.
