Mcb: miniature circuit breaker comes with max. 100A/10kA
rating earlier but but now it is available for 125A/16kA
rating. Based on thermal mechanism breaks the circuit under
short circuit condition.
Mccb: moulded case circuit breaker comes with upto
1000A/25kA rating. Based on thermal mechanism for overload
protection of load and magnetic mechanism for instant
tripping during short circuit.
Rccb: residual current circuit breaker, basically a kind of
ELCB which determines the difference between line and
neutral current,whenever it crosses the set value it trips.
Normally used in 3 phases while its single phase version is
known as RCD.
ELCB: earth leakage circuit breaker, basically used in DB
incomer is of two types, current operated and voltage
operated. In case of voltage operated one,the difference of
potential is measured between grounded spikes and terminal,
while in case of current operated one, you can call this a
RCCB.
MPCB: motor protection circuit breaker consist of separate
contactors used for protecting motors under over current
condition,which is generally caused due mechanical issues
of motors.
