摘要:
This part of IEC 60282 specifies requirements for expulsion fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and 60 Hz, and of rated voltages exceeding 1 000 V. Expulsion fuses are fuses in which the arc is extinguished by the expulsion effects of thegases produced by the *** fuses are classified according to the TRV (transient recovery voltage) capability inclasses A and *** standard covers only the performance of fuses, each one comprising a specifiedcombination of fuse-base, fuse-carrier and fuse-link which have been tested in accordancewith this standard; successful performance of other combinations cannot be implied from *** standard may also be used for non-expulsion fuses in which the interruption processwaits for natural current zero to clear the *** 1 See Clause 5andClause 12 for specific information regarding the selection of fuse *** 2 Fuses required for the protection of capacitors and for transformer circuit applications are subject toadditional requirements (see IEC 60549 [1]1 or IEC 60787 [2]).NOTE 3 This standard does not cover load-switching nor fault-making capabilities. Information regardingrequirements related to switching capabilities may be found in IEC 60265-1 [3].NOTE4 This standard does not cover aspects related to the level of noise, nor the emission of hot gases inherentto some types of expulsion fuses during the process of interruption of fault currents.
