1 Scope

This part of GB/T 9364 specifies the terms and definitions of small-sized fuse-links for special applications, general requirements, standard ratings, marking, Test, size and structure, electrical performance and other technical requirements and standard specifications.

This part applies to the rated voltage of not more than 1000V, rated current does not exceed 20A, rated breaking capacity of not more than 50kA of the melt Broken body.

This part does not apply to fuse links that are fully covered in the subsequent part of GB 13539.1.

This part does not apply to fuses for electrical installations intended for use under special conditions (eg corrosion or explosive atmospheres).

Special applications of small fuse links are not expected to be electrical equipment, electronic equipment, the end user replacement.

The purpose of this part is to develop a unified test scheme for small-sized fuse-links for special applications to verify the data given by the manufacturer (eg such as data on melting time and breaking capacity).
