Earth Leakage Circuit Breaker Diagram

Earth leakage circuit breaker or elcb.

Earth leakage circuit breaker 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. An voltage elcbs were first introduced about sixty years ago and current elcb was first introduced about forty years ago. Unlike previously studied rccb an elcb is a voltage operated device.

An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock. Forty years ago the first current eclbs were introduced and about sixty years ago the first voltage eclb was introduced. 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.

Generally the current sensing devices termed as rccb and voltage detecting devices named as earth leakage circuit breaker elcb. It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected.
