- Scope
- This standard applies to thermal links installed in electrical and electronic equipment and their components used in general indoor environments to prevent them from overheating in the event of a fault. NOTE 1 Equipment is not necessarily designed to generate heat. 2 The effect of preventing overheating is related to the installation position and installation method of the thermal fuse and the magnitude of the current it carries. 3 It should be noted that the external creepage distance and electrical clearance specified in Table 3 may be less than the requirements specified in some electrical or equipment standards in some cases. In this case, when the equipment is equipped with a thermal fuse, measures should be taken Make the creepage distance and electrical clearance reach the standard specified value of the equipment. As long as the climate and other immediate environment around the fuse-link are similar to the conditions specified in this standard. This standard also applies to thermal-links used in non-indoor conditions. This standard applies to simple-shaped thermal links, such as fuses or fuses, as long as the molten material discharged during operation does not affect the safe use of the equipment, especially for hand-held or portable equipment, regardless of its use position. affect their safe use. This standard applies to thermal fuses with AC rated voltage not exceeding 660V and rated current not exceeding 63A. This standard does not apply to thermal links used in extreme environmental conditions such as corrosive or explosive atmospheres. This standard is mainly applicable to thermal fuses on AC circuits with a frequency between 45Hz and 62Hz.
