Earth Leakage Relay Circuit Diagram

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.

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. Means it detects the earth leakage current and. For many years the voltage operated elcb and the differential current operated elcb were both referred to as elcbs because it was a simpler name to. 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.
