EC60947-4中接触器的使用类别标准的使用类别定义了接触器必须能接通和分断的电流值。这些电流依赖于：-负载被接通和分断的类型：鼠笼或滑环电机，电阻-发生接通或分断的条件：电机停止，起动或运行，反转，反接制动交流应用AC-1类别这个类别应用于所有功率因数大于等于0.95的交流负载中。例如：加热，照明，配电。AC-2类别这个类别应用于滑环电机的起动反接制动和寸动中。闭合时，接触器接通起动电流，大约2.5倍的电机额定电流。断开时，接触器必须分断起动电流，在电压小于等于主电源情况下。例如：部分起重行业。AC-3类别这个类别应用于分断正常起动的鼠笼电机。闭合时，接触器接通起动电流，大约7倍的电机额定电流。断开时，接触器分断电机的额定电流；这时接触器接线端的电压大约是主电源的20%分断不严酷。例如：所有标准的鼠笼电机：直梯，扶梯，传送带，挖土机，空压机，泵，搅拌机，空调等。AC-4类别这个类别包括鼠笼电机和滑环电机的反接制动和寸动。接触器接通5到7倍额定电机电流，分断更高电压下相同的电流，电机转速更低，那时电压与主电压一样分断很严酷。例如：印刷机械，拉丝机，塔机，起重，冶金行业。型号现货规格与选型资料如下：.
