CJ20交流接触器主要用于交流50Hz(60Hz)、额定电压至660V(个别等级至1140)、电流至630A的电力线路中供远距离频繁接通和分断电路以及控制交流电动机。
CJ20接触器适用于50Hz,额定电压660V电流至63A的电力系统中接通与分断电路并与适当的热继电器或电子式保护装置组合成电机起动器以保护可能发生过载的电路。
一、CJ20接触器适用条件:
1.CJ20接触器周围空气温度:a.周围空气温度上限不超过+40℃;b.周围空气温度24小时的平均值不超过+35℃;c.周围空气温度的下限值不低于-5℃。
2.CJ20接触器海拔高度:安装地点的海拔不超过2000m。
3.CJ20接触器大气条件:大气相对温度在最高温度+40℃时不超过50%;在较低温度下可以有较高的相对温度在最湿月的平均最低温度为+25℃时的月平均最大相对温度可为90%,并应考虑因温度变化发生在产品表面的凝露。
4.CJ20接触器安装条件:安装面与垂直面的倾斜度不大于±5°,供煤矿井下用产品按±15°考核。
二、CJ20交流接触器结构特征:
1.CJ20接触器为直动式、双断点、立体布置,结构简单紧凑。
2.CJ20接触器触头灭弧系统:全系列不同容量等级的接触器采用不同的灭弧结构。
3. CJ20接触器采用银基合金触头。
三、CJ20交流接触器主要技术参数:
1.电寿命:CJ20 、16、25、40为100万次。
2.机械寿命:CJ20 、16、25、40、63、100、160为1000万次。
