IEC/EN60947-4-1BC6-30-10
如果控制线路比较简单，所用接触器的数量较少，则交流接触器线圈的额定电压一般直接选用380V或220V。如果控制线路比较复杂，使用的电器又比较多，为了安全起见，线圈的额定电压可选低一些，这时需要加一个控制变压器。直流接触器线圈的额定电压应视控制回路的情况而定。而一系列、同一容量等级的接触器，其线圈的额定电压有好几种，可以选线圈的额定电压和直流控制电路的电压一致。直流接触器的线圈是加直流电压，交流接触器的线圈一般是加交流电压。有时为了提高接触器的*操作频率，交流接触器也有采用直流线圈的。如果把直流电压的线圈加上交流电压，因阻挠太大，电流太小，则接触器往往不吸合。如果将交流电压的线圈加上直流电压，则因电阻太小，电流太大，会烧坏线圈。交流接触器的电压等级要和负载相同，选用的接触器类型要和负载相适应。负载的计算电流要符合接触器的容量等级，即计算电流小于等于接触器的额定工作电流。接触器的接通电流大于负载的启动电流，分断电流大于负载运行时分断需要电流，负载的计算电流要考虑实际工作环境和工况，对于启动时间长的负载，半小时峰值电流不能过约定发热电流。
