Scope

This Standard specifies requirements for high voltage expulsion fuses, including boric acid type fuses, disconnector fuses, and drop-out fuses designed for use on alternating current systems of 50 Hz and 60 Hz and of rated voltages exceeding 1000 V up to and including 72.5 kV.

NOTES:
1. Fuses required for the protection of capacitors are subject to additional requirements (see IEC 549).
2. This Standard covers only the performance of fuses each comprising a specific fuse-base, fuse-carrier and fuse-link which have been tested in accordance with this Standard, and no guarantee of the performance of other combinations can be implied from this Standard.
3. For guidance on the presentation of characteristics, special tests and test conditions see Appendix C.
