MCB meance Moulded Circuit Breaker also called as miniature
circuit breaker which are small capacity ( low voltage )
breakers and these too are moulded. So MCB is a breaker but
moulded(sealed). The breaker is the term used to a unit
which breaks (opens) the circuit above its rated flow of
current. it has the characteristic and ability to self
operate and isolate(break) the circuit if there is a fault
down the line. Circuit breakers are used to connect the
LOAD to the power circuit(line). Once the breaker has
opened it can not get ON by itself. It is to be actuated
again.Thats why we find a certain breaking capacity value
in MCBs in Kilo Amps.For example for light/fan loads the
MCBs rating is 6Amps which have a breaking capacity of
9Kilo amps whereas power points for ACs need 15Amp MCBs
with breaking capacity of 9 t0 12 Kilo Amps.depends upon
the manufacturers specifications.
As on date best MCBs available in market are:-
MDS,L&T,Siemens. Others of second grade are:-
Havells,Standard,HPL,Indo-Asian.
