voltage, earth fault, over current & its very sensitive.

Fuses : most of the fuses used only at low current rating &
not using at LT panels.

Breakers : its used more high current ratings & using at
all LT panels.

Fuses : fuses made up of Bismuth, Cadmium, Silver & chana
clay.

Breakers : made up of totaly mechanical systems & trpping
