1 Scope
This part of IEC 60127 is applicable to fuse-holders for miniature cartridge fuse-links according to IEC 60127‑2 and sub-miniature fuse-links according to IEC 60127‑3 for the protection of electric appliances, electronic equipment and component parts
thereof, normally intended for use indoors.
Examples of fuse-holder types with different features are given in Table 1.

NOTE This list is not intended to be comprehensive and fuse-holders which are not listed are not necessarily excluded from the scope.
This part of IEC 60127 applies to fuse-holders with:
-
— a maximum rated current of 16 A; and
-
— a maximum rated voltage of 1 500 V d.c. or 1 000 V a.c.; and
-
— for use up to 2 000 m above sea-level, unless otherwise specified.
The object of this standard is to establish uniform requirements for safety and the
assessment of electrical, mechanical, thermal and climatic properties of fuse-holders and the compatibility between fuse-holders and fuse-links.
