Type B :
MCBs react quickly to overloads, and are set to trip
when the current passing through them is between 3 and 4.5
times the normal full load current.
Type C :
MCBs react more slowly, and are recommended for
applications involving inductive loads with high inrush
currents, such as fluorescent lighting installations. Type C
MCBs are set to trip at between 5 and 10 times the normal
full load current.
Type D :
MCBs are slower still, and are set to trip at between
10 and 20 times the normal full load current. They are
recommended only for circuits with very high inrush
currents, such as those feeding transformers and welding
machines.
