电气延时继电器 1VCF339750S7909， Auxiliary relay D-KT-KFT for time delay 0,5-3s of undervoltage release YU-MU-MBU aux. voltage 110-132Vdc/ac for HD4, VD4, eVD4, Vmax， 出口版，IEC。电气延时装置必须安装在断路器的外部。它使得断路器可在可调的、预先设定好的时间后分闸。如果此装置未加电，则断路器无法合闸。电气延时装置必须与相同工作电压的欠压脱扣器配合使用。 欠压脱扣器可与电气延时装置（-KT）配合使用，可防止在二次电源很短时间的暂时性下降或失电的情况下断路器误分闸。可调的延时时间 2）：0.5-1-1.5-2-3 s 。
