The circuitry in the chart is a zero crossing drive circuitry. When passing the zero-passage place of ealternating voltage, the zero crossing drive can control the ON or OFF of the current to minish surge caused by switch and let up the electromagnetism jam to the surrounding equipments. In the circuitry, ZNR is a sensitive component, which is used as absorbing surge from circuitry to protect power components.
