MCB-ELCB-MCCB-RCCB-RCBO me kya difference hai / ELCB kaise kaam karta hai

MCB Miniature Circuit Breaker [ MCB ]
MCB Definition: An MCB is defined as an automatically operated switch that protects low voltage electrical circuits from excess current due to overload or short circuit.

ELCB
What is an ELCB? Types, Working, and Application of Earth Leakage Circuit Breaker
ELCB or Earth Leakage Circuit Breaker is a protection device that protects against earth leakage. Initially, the earth leakage circuit breaker were voltage detection devices, now they are switched to current sensing devices. The current ELCB is renamed as RCCB or RCD while the voltage ELCBs are still known as ELCB but they are obsolete
