Earth Leakage Relay Wiring Diagram. 1 x spdt1 x spno relay outputs. In a situation when there is fault or a leakage to earth in the load circuit or anywhere between the load circuit and the output connection of the rcb circuit can you provide me the wiring diagramfor house wiring.
To monitor earth leakage current and to operate an associated relay at a preset current. The discussed earth leakage circuit breaker diagrams will monitor the leakage current level of the earthing line of your house electrical sockets and will trip the appliances as soon a fault is detected. Type a earth leakage relay.
Working principle of earth leakage relay.
Earth leakage relay elr transmits a signal to activate the trip coil of the mccbacbocb contactor in the event of earth leakage resulting in automatic isolation of the electrical power system. The relay detects earth leakage currents with the aid of the external core balance current transformer. Earth leakage relays are used to sense small magnitude of currents. 2 simple earth leakage circuit breaker elcb explained.
