Multi-functional Leakage Protection Switch Circuit
The multi-functional leakage protection switch uses Nissan M54122 which can constitute multifunctional leakage protection switch.The magnetic field is generated by flowing through front line and zero line and it is cancelled out and it does not produce AC current when there are leakage or an electric shock.And coil is produced and 7 feet produces high voltage level,which triggers controlled silicon and makes the relay action cut off power supply. Overvoltage protection is composed of Ru1,Ru2,Ru4,Ru5 and D1.Thermistor Ru1 is used to absorb the overvoltage caused by lightning or center line fault.
