2.2.3. MELTING FUSE
If enabled, after the programmed closure cycle (1 to 3), the protection changes
automatically the protection group it is working with, enabling then a group previously
programmed by the user. This settings change enables the increase of the protection
functions operation times and allows the protection fuses of the installation blow up
before the breaker acts. When the ongoing cycle is finished the original group is
activated again.
