Forty years ago the first current eclbs were introduced and about sixty years ago the first voltage eclb was introduced.
Electrical earth leakage circuit breaker diagram.
The needs of these devices arise because of the number increasing in injuries as well as deaths because of electric shock.
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.
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.
Current earth leakage current earth leakage circuit breaker current elcb.
Means it detects the earth leakage current and.
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.

The diagram below shows how a single phase elcb circuit looks like.
It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected.
Generally the current sensing devices termed as rccb and voltage detecting devices named as earth leakage circuit breaker elcb.
The added earth leakage detection helps prevent electrical shock and electrical fires that are caused by a short circuit or overload in the control panel with an automatic shut off when leakage is detected.
Elcb is a short for earth leakage circuit breaker.
We offer motor rated circuit breakers that ranges from fractional amperage up to 225 amps.
Early earth leakage circuit breakers are voltage detecting devices which are now switched by current sensing devices rcd rccb.
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.
