Answer Posted / karthik.j
MCB means Miniature Circuit Breaker -- it is used for upto
100Amps in the motor feeders.
MCCB menas Moulded case Circuit Breaker -- it is used for
25oAmps to 800Amps in the motor feeders.
ELCB means Earth Leakage Circuit Breaker -- it is used to
trip the Circuit breaker if any leakage fault occured means.
RCCB means Residual Current Circuit Breaker -- A residual
current device (RCD), or residual current
circuit breaker (RCCB), is an electrical wiring device that
disconnects a circuit whenever it detects that the electric
current is not balanced between the phase ("hot") conductor
and the neutral conductor. Such an imbalance is sometimes
caused by current leakage through the body of a person who
is grounded and accidentally touching the energized part of
the circuit.
