Revision Standard - Superseded.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.
This standard specifies design test requirements for high-voltage (above 1000 V) fuses, distribution enclosed 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 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 e) Fuse supports of the type intended for use with distribution and power class fuses, and fuse disconnecting switches f) Fuse and disconnecting cutouts g) Disconnecting devices created by the use of a removable switch blade in a distribution or power class fuse support h) Distribution class enclosed single-pole air switches i) Distribution class and power class expulsion, current-limiting, and combination types of external capacitor fuses used with a capacitor unit, groups of units, or capacitor banks j) Backup current-limiting fuses ("motor-starter fuses") used in conjunction with high-voltage Class E2 motor starters (see ANSI/UL 347-2000 [B1])1 k) Fuse links when used exclusively with distribution class and power class fuses, and distribution class and power class fuse disconnecting switches l) Item a) through item d) and item f) through item i) having integral load-break means
This standard specifies the minimum testing requirements for fuses and related devices. Such standardization is needed to ensure uniform minimum product testing for devices within the document scope. Test areas covered are based on historical experience.
