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
