If ample voltage seems across the elcb s sense coil it will turn off the power and remain.
Earth leakage relay circuit diagram.
An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock.
Means it detects the earth leakage current and.
Current earth leakage current earth leakage circuit breaker current elcb.
An voltage elcbs were first introduced about sixty years ago and current elcb was first introduced about forty years ago.
It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected.
An elcb is a specific type of latching relay that has a structure s incoming mains power associated through its switching contacts so that the circuit breaker detaches the power in an unsafe condition the elcb notices fault currents of human or animal to the earth wire in the connection it guards.
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.
