Miniature circuit breaker or MCB.
It is an Electrical switch designed to protect an electrical circuit from damage caused by (Overcurrent)/(overload) or (short circuit). Its basic function is to interrupt current flow after Protective relays detect faults condition. Unlike a fuse, which operates once and then must ben replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.
Handling MCB is more electrically safe than fuse.
Because of to many advantages of MCB over fuse units, in modern low voltage electrical network, miniature circuit breaker is mostly used instead of backdated fuse unit.
The disadvantage is that,it's a bit costlier than the fuse or fuse wire.

oh really? then surely ur answer will b deleted coz if we can get the answer frm the net then whats the use of brainly?
For ur kind info kidoo even the net firm is written by some human specie, IF U HERE COMPARE,THEN THAT'S UR WISH.
ik but u hv to use ur common sense nd em not a kiddooo
and if u r copying frm the net that means u dont know what MCBs actually are
I can easily sense that. :-p
u dont seem to EASILY SENSE THAT
I hope u atleast know or remember,who posted the question.
hahah
lets not fight nymore.whats ur gender

MAIN COURSE BOOK of talking about english. its function is nothing but gives us knowledge.
Scientifically, MCB stands for miniature circuit breakers. these days,MCBs are being used in place of fuses.these are switches which automatically turn off when current in a circuit exceeds its safe limit.
the picture above is of an MCB. refer to it too.
hope it helps
plz mark as brainliest
