ELCB - Earth Leakage Circuit Breaker - Senses the leakage
current between earth and phase .
RCCB - Residual Current Circuit breaker - Senses the total
flow of current and compare with the return current through
Neutral and functions on the difference of this current
ELCB and RCCB are available in current sensing capcity of
30, 100, 300 mA and in three phases and Single Phase.
Currently RCCB is considered as superior to ELCB
MCB - Miniature Circuit breaker - Only functions on overload
