Earth Leakage Circuit Breaker Diagram

Generally the current sensing devices termed as rccb and voltage detecting devices named as earth leakage circuit breaker elcb.
Earth leakage circuit breaker diagram. 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. Means it detects the earth leakage current and. 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.
Forty years ago the first current eclbs were introduced and about sixty years ago the first voltage eclb was introduced. Early earth leakage circuit breakers are voltage detecting devices which are now switched by current sensing devices rcd rccb. It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected. Current earth leakage current earth leakage circuit breaker current 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.
