Earth Leakage Circuit Breaker Diagram

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

Earth leakage circuit breaker diagram. Earth leakage circuit breaker or elcb. 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. Generally the current sensing devices termed as rccb and voltage detecting devices named as earth leakage circuit breaker elcb.

An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock. Current earth leakage current earth leakage circuit breaker current elcb. 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.
