電氣延時繼電器Auxiliary relay D-KT-KFT for time delay 0,5-3s of undervoltage release YU-MU-MBU aux. voltage 48Vdc/ac for HD4, VD4, eVD4, Vmax出口版，IEC。電氣延時裝置必須安裝在斷路器的外部。它使得斷路器可在可調的、預先設定好的時間后分閘。如果此裝置未加電，則斷路器無法合閘。電氣延時裝置必須與相同工作電壓的欠壓脫扣器配合使用。 欠壓脫扣器可與電氣延時裝置（-KT）配合使用，可防止在二次電源很短時間的暫時性下降或失電的情況下斷路器誤分閘。可調的延時時間 2）：0.5-1-1.5-2-3 s 。
