How earth leakage circuit breaker work working of elcb working of rccb an eclb is one kind of safety device used for installing an electrical device with. Forty years ago the first current eclbs were introduced and about sixty years ago the first voltage eclb was introduced.

What is elcb earth leakage circuit breaker elcb stands for earth leakage circuit breaker and it is used for protecting a person from electric shock and injury. Early earth leakage circuit breakers are voltage detecting devices which are now switched by current sensing devices rcd rccb. Electrical wiring diagram of a 230v single phase 63a distribution board consumer unit with rcd for ac units lighting 13a radial circuits. 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.

Generally the current sensing devices termed as rccb and voltage detecting devices named as earth leakage circuit breaker elcb. 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 earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock.

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. It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected. We offer motor rated circuit breakers that ranges from fractional amperage up to 225 amps. Earth leakage circuit breaker or elcb.

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.
