An voltage elcbs were first introduced about sixty years ago and current elcb was first introduced about forty years ago.

Earth leakage relay circuit diagram.

Means it detects the earth leakage current and. An elcb is a specific type of latching relay that has a structure s incoming mains power associated through its switching contacts so that the circuit breaker detaches the power in an unsafe condition the elcb notices fault currents of human or animal to the earth wire in the connection it guards. If ample voltage seems across the elcb s sense coil it will turn off the power and remain. It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected.

If any current leaks from any electrical installation there must be any insulation failure in the electrical circuit it must be properly detected and prevented otherwise there may be a high chance of electrical shock if anyone touches the installation an earth leakage circuit breaker does it efficiently. Current earth leakage current earth leakage circuit breaker current elcb. Earth leakage circuit breaker or elcb.
