what are the differences between MCB and MCCB ?..

Answer / venkat iyer

MCB is a miniature circuit breaker that can safely break
only a small amount of short circuit current. The O/L and
S/C protection releases are factory calibrated and is not
adjustable at installation points. Max. available in India
is 10 KA. This its application is at the lowest end of
power utilisation such as small power, lighting and for
some small motor applications.

MCCB is a moulded case circuit breaker capable of switching
on and off a large amount of power. It is designed to carry
large amount of making current and breaking current. It
comes with -accessories like hunt trip, UV release,
adjustable short circuit and overload protection releases,
earth fault release etc.

what are the differences between MCB and MCCB ?..

Answer / d.shirisha

MCCBs and MCBs are protecting Devices for low power
distributions(LOW TENTION PANELS). MCB is used for lower
Amphere ratings and it is starting from single pole up to
four pole.MCCB is used for lower as well as higher Amphere
ratings it is in three pole and four pole...

Answer / chirag vyas

it's simple the MCBs used for small current breaking
whereas MCCBs for large current/Arc supression.
Both provides short ckt/magnetic protection.

Answer / md hasmat khan

(MCB) Stands for Miniature Circuit Breaker Which is used in
low current capacity MCB is not having the adjesement of
protection.
(MCCB) Stands for Moulded Case Circuit breaker Which is
used for High current capacity but MCCB over load, short
circuit, and earth fault.

Answer / subir kumar manna

MCB is a small type of mains power operator , thats
function is miniature cirquite breaker. overload protection
short circquite protection. there cappacityes is low current
carrieng capacityes .
MCCB that is a moulded case cirquite breaker, internaly
function of mccb any hunting trip and under voltage realese
over load realese , short cirquite realese , earth foult rea
lese . mccb is a large current carring capacities .
