适用范围

This International Standard 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 1000 V. Expulsion fuses are fuses in which the arc is extinguished by the expulsion effects of the gases produced by the arc. Expulsion fuses are classified according to the TRV (transient recovery voltage) capability in classes A, B and C. This standard covers only the performance of fuses, each one comprising a specified combination of fuse-base, fuse-carrier, and fuse-link which have been tested in accordance with this standard; and successful performance of other combinations cannot be implied from this standard. This standard may also be used for non-expulsion fuses in which the interruption process waits for natural current zero to clear the circuit. NOTE 1 - See clause 5 and application guide for specific information regarding the selection of fuse class. NOTE 2 - Fuses required for the protection of capacitors and for transformer circuit applications are subject to additional requirements (see IEC 60549 or IEC 60787). NOTE 3 - This standard does not cover load-switching nor fault-making capabilities. Information regarding requirements related to switching capabilities may be found in IEC 60265-1. NOTE 4 - This standard does not cover aspects related to the level of noise, nor the emission of hot gases inherent to some types of expulsion fuses during the process of interruption of fault currents.
