Earth leakage circuit breaker diagram.

An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock. An earth leakage circuit breaker is a safety device used in electrical circuits with high earth impedance to prevent the risk of electrical shock. Earth leakage circuit breaker or elcb. Means it detects the earth leakage current and.

Unlike previously studied rccb an elcb is a voltage operated device. Early earth leakage circuit breakers are voltage detecting devices which are now switched by current sensing devices rcd rccb. 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. An voltage elcbs were first introduced about sixty years ago and current elcb was first introduced about forty years ago.

It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected. 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.
