CJ20交流接觸器主要用于交流50Hz(60Hz)、額定電壓至660V(個別等級至1140)、電流至630A的電力線路中供遠距離頻繁接通和分斷電路以及控制交流電動機。
CJ20接觸器適用于50Hz,額定電壓660V電流至63A的電力系統中接通與分斷電路并與適當的熱繼電器或電子式保護裝置組合成電機起動器以保護可能發生過載的電路。
一、CJ20接觸器適用條件:
1.CJ20接觸器周圍空氣溫度:a.周圍空氣溫度上限不超過+40℃;b.周圍空氣溫度24小時的平均值不超過+35℃;c.周圍空氣溫度的下限值不低于-5℃。
2.CJ20接觸器海拔高度:安裝地點的海拔不超過2000m。
3.CJ20接觸器大氣條件:大氣相對溫度在最高溫度+40℃時不超過50%;在較低溫度下可以有較高的相對溫度在最濕月的平均最低溫度為+25℃時的月平均最大相對溫度可為90%,并應考慮因溫度變化發生在產品表面的凝露。
4.CJ20接觸器安裝條件:安裝面與垂直面的傾斜度不大于±5°,供煤礦井下用產品按±15°考核。
二、CJ20交流接觸器結構特征:
