Earth Leakage Relay Connection Diagram

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.

Earth leakage relay connection diagram.

Combined over current earth fault relay dp 34. Earth leakage relay elr transmits a signal to activate the trip coil of the mccb acb ocb contactor in the event of earth leakage resulting in automatic isolation of the electrical power system. Earth leakage relays earth leakage relays. See connection diagram 24 115 230v ac 85 115 of un all ac supplies are galvanically isolated between the supply and the toroid and remote test reset connections.

Type a earth leakage relay. Connection check open short total trip count information self reclosing auto reset programmable relay output programmable software lock. Earth leakage relay dp 10. 48 x 48mm panel mount.

1 x spdt 1 x spno relay outputs. Earth leakage circuit breaker or elcb. 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. Advanced power quality network analyzer.

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. 16 earth leakage relays technical characteristics page 16 6 and 7 wiring diagrams page 16 5 dimensions page 16 4 general characteristics earth leakage relay type a 2 output relays each with changeover contact configurable 2 tripping or 1 tripping and 1 alarm configurable fail safe prealarm and operation automatic toroid. Selectable trip level 0 03 30a and time delay 0 10s local and optional remote test reset buttons.

Over current relay dp 23 dp 33. Earth fault relay dp 21 dp 31. If ample voltage seems across the elcb s sense coil it will turn off the power and remain.
