Elcb: An ELCB is a specialised

An ELCB is a specialised type of latching relay that has a building's incoming mains power connected through its switching contacts so that the ELCB disconnects the power when earth leakage is detected. The ELCB detects fault currents between line and earth (ground) conductors within the portion of the installation it protects. If sufficient characteristics of a fault appear across the ELCB 's sensing mechanism, then it will switch off the power, and remain off until manually reset.

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. In this article, we are going to discuss ELCB in detail with both types. MCB, MCCB, RCCB, & ELCB are circuit breakers but designed for serving a different purpose. Let's understand the difference among all in detail here.
