Earth leakage relay working principle pdf. An voltage elcbs were first introduced about sixty years ago and current elcb was first introduced about forty years ago. Manufactures the most trusted dependable earth leakage relays for more than 15 years and they are time tested h series earth leakage are different from other normal leakage relays. If ample voltage seems across the elcb s sense coil it will turn off the power and remain. 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.

The working principle of voltage elcb is quite simple. Earth leakage relay for non linear loads like ups invertor drives other applications h series elr.
