Load conditions of fuses

The load profile of a fuse is the amount of current load that the fuse is subjected to during actual use. The load profile of a fuse has a significant impact on its life and performance. The load condition of the fuse should be within its rated current.
If the fuse is subjected to overload current for a long period of time, its internal materials will be damaged, resulting in a shortened fuse life. When selecting a fuse, a suitable fuse should be chosen according to the load condition to ensure its proper operation and life.
The fuse should also avoid abnormal conditions such as frequent switching and short circuiting to avoid damage to the fuse and affect its life.

Maintenance of the fuse

Maintenance of the fuse has a significant impact on its life and performance. Correct maintenance can extend the service life of the fuse and ensure its normal operation.
Fuses should be inspected and tested regularly to ensure that they work properly. The inspection includes whether there is any damage to the appearance of the fuse, whether the contactor is normal, and whether the connection is firm. Tests include the fuse’s action time, action current and so on.
The fuse should be cleaned and lubricated regularly to ensure its normal operation. Clean the fuse surface with a clean cloth and avoid using corrosive solvents. Lubrication should use the appropriate amount of lubricating oil or grease.
Fuses should be maintained and replaced in accordance with specified procedures to avoid incorrect operation and damage to the fuse.
The service life and impact of the fuse is affected by a variety of factors, including the design life of the fuse, the use of the environment, load conditions, maintenance and so on. Proper selection of suitable fuses, provision of a good use environment, avoidance of overload and abnormal conditions, regular inspection and maintenance can prolong the service life of the fuse and ensure its normal operation.
