This Malaysian Standard is applicable to fuses incorporating enclosed current-limiting fuse-links
with rated breaking capacities of not less than 6 kA, intended for protecting power-frequency
a.c. circuits of nominal voltages not exceeding 1 000 V or d.c. circuits of nominal voltages not
exceeding 1 500 V.
Subsequent parts of this standard, referred to herein, cover supplementary requirements for
such fuses intended for specific conditions of use or applications.
Fuse-links intended to be included in fuse-switch combinations according to IEC 60947-3
should also comply with the following requirements.
NOTE 1 For "a" fuse-links, details of performance (see 2.2.4) on d.c. circuits should be subject to agreement between user and manufacturer.
NOTE 2 Modifications of, and supplements to, this standard required for certain types of fuses for particular applications – for example, certain fuses for rolling stock, or fuses for high-frequency circuits – will be covered, if necessar
