法國(guó)施耐德Schneider交流接觸器LC1D80M7C
1.用法：LC1-D系列交流接觸器主要用于交流50Hz(或60Hz)
額定絕緣電壓為690V
在AC-3使用類別下額定電壓為380V時(shí)額定工作電流至95A的電路中
供遠(yuǎn)距離接通和分?jǐn)嚯娐?br />并可與適當(dāng)?shù)臒徇^載繼電器組成電磁起動(dòng)器以保護(hù)可能發(fā)生過負(fù)荷的電路
2.原理：LC1-D系列交流接觸器工作原理
當(dāng)接觸器電磁線圈不通電
彈簧的反作用力和銜鐵芯的自重使主觸點(diǎn)保持?jǐn)嚅_位置
當(dāng)電磁線圈通過控制回路接通控制電壓（一般為額定電壓)時(shí)
電磁力克服彈簧的反作用力將銜鐵吸向靜鐵心，帶動(dòng)主觸點(diǎn)閉合
接通電路，輔助接點(diǎn)隨之動(dòng)作
