MCB - Miniature Circuit breaker, is having overload and
s.c. protection & used in domestic application
MCCB - Moulded case Circuit breaker, is having overload and
s.c. protection & used in Industrial application & Having
high s.c. capacity
RCCB : Residual current operated circuit breaker, is used
for protection against electric shock
ELCB : Earth leakage circuit breaker & is same as RCCB
MPCB : Motor protection circuit breaker, is used for
protection of motor, having s.c. and overload protection
more effective to protect motor

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
