An Earth Leakage Circuit Breaker (ELCB) is an electrical device that disconneCts proteCted circuit whenever it detects unbalance current between the phase conductor and the neutral conductor. Example of the unbalance may caused by current leakage through die bixly of a person Who is grounded when accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. ELCB are designed t() disconneCt this fa\llt fast enough to mitigate the harm caused by such shocks. Currently, there is no Earth Leakage Circuit Breaker (ELCB) with allto re-Closer featlll"es iii the market. The current ELCB tliat available in the market is a manual type and cannot differentiate between temporary distlll"bances llrid permanent fa\llts, meaning tliat, if a distllfbaiiee or falllt occurs ()n the protected area (house), the protection system will force ELCB to trip. One of the disadvantage ()fthe common ELCB is that, it is cannot tllfn oil the power sllpply back to the normal operation condition although only a short disturbance occurs. Such disturbilitce is lightnilig strike on the transmission line in the disti'iblltion site near to the protected area. To tum the power back to normal operation, consumers need to do that iiiaiillally. To overcome tfiis problem, IitteJiigeitt Ellftli Leakage Circuit Breaker (1-ELCB) has been developed. This device was designed to auto-reset ELCB when sfiort distllfbllrice occllr aiid send alert signal to user ifj)erffianeitt falllt occur.
