Answer / puneet kumar

whenever a input current flows above the certain specified
value then MCB interrupt the phase i.e. break the circuit.
This certain value is define by rating of MCB connected on
a particular ciruit(for light circuit or power circuit).

Answer / shenba

MCB- miniature circuit breaker,
it breaks the circuit when there is over current flows on
the line which exceeds the crt ratting of mcb used.
ITs also due to when load connected having any short
circuit bpms then mcb trips or breaks the ckt.

helps to prevent fire or short circuit.

Answer / santhi swaroop

MCB means miniature circuit breaker.it compares current
between phase and neutral conductors and difference exist
than interrupt the phase i.e. break the circuit. simply it
is differential coil circuit breaker

Answer / sudarshan singh

MCB mean is moulded circuit breaker. It is used to triping
the over current against use to spacify mcb rating. MCB is
many type as B-Class, C-Class & D-Class. C-Class type mcb
mostly used in industrial area.
