Breaking capacity of fuses
- Sep 10, 2018 -

When the current between the conventional non-fusing current and the rated breaking capacity (current) specified by the relevant standard acts on the fuse, the fuse should be able to act satisfactorily and not endanger the surrounding environment. The expected fault current of the circuit in which the fuse is placed must be less than the rated breaking capacity current specified by the standard, otherwise, the phenomenon of continuous arcing, ignition, fuse burning, melting of the contact pieces, and the inability to identify the fuse mark will occur when the fuse is broken. Of course, inferior fuse breaking ability can not reach the requirements of the standard, the same will happen when using the above hazards.
