電磁接觸器請教

Jun 21st 2014, 13:39

你買的這顆接觸器(又稱MC)比較小只有一組NO(俗稱A接點)接點

線圈通電激磁後主電路會導通

每個接點都是獨立運作沒錯

13/14接點才叫做輔助接點

如其名是用來輔助的可通過電流較小不可當作主接點

例如可以用來接指示燈

MC激磁時指示燈會亮

可以很容易得知MC的狀態

或是外接其他的器具(輔助電驛,時間電驛......)

來達成預期的控制

要外加NC(B接點)不過MC本身構造是無法改變

但可以透或外加的方式實現

這顆士林電機的MC可以外加輔助接點組

安裝的位置在MC的上方黑色部分(記得好像卡進去就好)

士電的網站參考一下
