Answer Posted / mukesh sharma
Tripping devices are circuit breaker,mcb,mccb,rccb,elcb
MCB: Miniature circuit breaker
MCCB: Molded case circuit breaker
RCCB: Residule current circuit breaker
ELCB: Earth leakage circuit breaker.
mcb can be used up to certain level of current it can also
used as a switch but it can Connect only on single conductor
or wire for two or more wires we can use different circuits
manufactured by multiple mcb like Dp,Tp Tpn.
mccb it can be used at three wires for large ammount of
current flowing (above mcb rating) usually above 100A current.
mccb & elcb both are used for human protection but tripping
method of both is different elcb will trip by sensing
cuntunity between phase and earth when ever mccv will trip
if there is a difference in current flowing between phase &
neutral more than or equal to 30mA basically mccb is advance
version of elcb & it is letence.
in my openian mccb is more better than mccb.
