Electrical Earth Leakage Circuit Breaker Diagram

Early earth leakage circuit breakers are voltage detecting devices which are now switched by current sensing devices rcd rccb.

Electrical earth leakage circuit breaker diagram.

Generally the current sensing devices termed as rccb and voltage detecting devices named as earth leakage circuit breaker elcb. Forty years ago the first current eclbs were introduced and about sixty years ago the first voltage eclb was introduced. An voltage elcbs were first introduced about sixty years ago and current elcb was first introduced about forty years ago. Means it detects the earth leakage current and.

However before i get down to explain more please take note that i am using the name elcb as a generic name just like a circuit breaker.

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

It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected. The diagram below shows how a single phase elcb circuit looks like. Elcb is a short for earth leakage circuit breaker. 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.

Earth leakage circuit breaker or elcb. The size of the fuse and circuit breaker are similar to use but circuit breaker is more safe to use as compared to fuses due to automatic operation as you can reset it again if it trips ever. 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.
