請注意 : 你幅圖係錯既, 請參考雪地火花既圖圖片參考：http://imgcld.yimg.com/8/n/HA00639401/o/701001030015013873390270.jpg

因爲ZCT繞線方向錯佐，冇平衡作用而產生電流，所以會立刻跳制，明未？

繼電器 = Relay
TRIP COIL 係 ACB 或 MCCB 内既 STC
當然 RCD 内都有TRIP COIL

係佢划錯佐
應該係TRIP COIL

to be clear,
in a L-N Circuit,since there are series wiring,so the current of L equal to The current of N.
when its leakage,some current pass through the earth,so the current of L and N are not equal.the mechanism had been detected,the RCD will break the circuit in atleast 0.4s.

博士果然細心，抵讚！

博士，TRIP COIL同繼電器有乜嘢唔同呢？

RCD Residual - Current Device
RCD 是用一個差異電流變壓器, 偵測兩個導體之間電流平衡( 火線與中性線之間的電流差異), 如電流不平衡時候, Trip Coil 在25-40 微秒內切斷電流.
